Rare gases have such a wide range of applications

Rare gases are a general term for gases such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). In the past, people believed that these gases did not react with other substances, so they were also called "inert gases."In fact, although these gases do not account for a high proportion in the air, they are indispensable in our modern life. In this issue, Jiayuan will talk about their common uses.1.As protective gasBecause the chemical properties of rare gases are very inactive, argon is often used as a shielding gas to isolate the air when welding precision parts or active metals (such as magnesium and aluminum) to prevent the metal from reacting with other substances at high temperatures.Iridium, the nuclear fuel of nuclear reactors, which oxidizes rapidly in the air, also needs to be machined under the protection of argon.In order to extend the service life of the light bulb, adding argon gas into the light bulb can reduce the evaporation of the tungsten filament and prevent the tungsten filament from oxidation.2. As an electric light sourceRare gases emit light of different colors when electricity is applied. The world's first neon light was made of neon. The red light emitted by neon has strong transmittance in the air and can pass through thick fog. Therefore, neon lights are often used as beacons in airports, ports, and water and land transportation routes. Argon or helium is filled into the tube, which emits light of light blue or light red when electricity is applied. Filling a mixture of helium, neon, and argon with different contents into the tube can make colorful neon lights.The commonly used fluorescent lamp is made by filling a small amount of mercury and argon gas in the lamp tube and applying fluorescent material (such as calcium halophosphate) on the inner wall. When the power is turned on, the discharge of mercury vapor generates ultraviolet rays in the tube, which stimulates the fluorescent material to emit visible light similar to sunlight, so it is also called a fluorescent lamp.When powered on, a high-voltage long-arc lamp filled with xenon can emit strong light that is tens of thousands times stronger than a fluorescent lamp. Therefore, it is called an "artificial little sun" and can be used for squares, stadiums, airports and other lighting. Neon lights, krypton gas, and xenon gas can also be used in laser technology.3. Medical treatment   Xenon lamps have high ultraviolet radiation and are used in medical technology. Xenon gas dissolves in cell oil, causing cell anesthesia and swelling, thereby temporarily stopping the action of nerve endings and achieving anesthesia. As an anesthetic without side effects, people have tried a mixture of 80% xenon and 20% oxygen.Isotopes of krypton and xenon are also used to measure cerebral blood flow, etc.4. Making Artificial AirHelium and oxygen are mixed into artificial air, which divers can breathe. Because in the deep sea with greater pressure, if you breathe with ordinary air, more nitrogen will be dissolved in the blood. When the diver rises from the deep sea and gradually restores the normal pressure in the body, the nitrogen dissolved in the blood should be released to form bubbles, blocking the microvessels and causing "gas stasis". The solubility of helium in the blood is much lower than that of nitrogen. If the above phenomenon does not occur, but the ordinary air is replaced by a mixture of helium and oxygen (artificial air). 5. InflationHelium is the lightest gas besides hydrogen. Hydrogen is flammable and explosive, while helium is a colorless, odorless, inert gas. It is chemically inactive. Generally speaking, it is difficult to react with other substances. Helium has been used to fill balloons and airships instead of hydrogen. 6. Can produce a variety of mixed gas lasersHelium-neon laser is one of them. Helium-neon mixed gas is sealed in a special quartz tube. Under the encouragement of an external high-frequency oscillator, inelastic collisions occur between atoms of the mixed gas, and energy transfer occurs between the stimulated atoms, resulting in electronic transitions and emitting stimulated radiation waves and near-infrared light corresponding to the transitions. Helium-neon lasers can be used for measurement and communication.7. Low temperatureThe boiling point of liquid helium is -269℃, which is the most difficult to liquefy of all gases. Using liquid helium, ultra-low temperatures close to absolute zero (-273.15℃) can be achieved. Liquid helium is an ordinary liquid with the properties of ordinary liquids. Liquid helium below 2.2 thousand is a superfluid with many abnormal properties. For example, it has superconductivity and low viscosity. Its viscosity is 1% of the viscosity of hydrogen. Liquid helium can flow upward along the inner wall of the container and then slowly flow along the outer wall of the container. This phenomenon is of great significance to the research and verification of quantum theory. In today's era of rapid technological development, rare gases have been widely used in many fields due to their unique and excellent properties. Whether in the lighting industry, they provide us with bright and energy-saving light sources; or in the electronic chip manufacturing process, they serve as key protective gases and etching gases to help produce high-precision chips; or in the medical field, they play an indispensable role in specific diagnostic and treatment methods; and in high-end technological frontiers such as aerospace, they provide guarantees for the stable operation of various precision instruments and equipment.

Hexafluorobutadiene: An emerging key material for the semiconductor industry

The semiconductor manufacturing process has extremely high requirements for etching gases. As chip manufacturing processes continue to shrink, the demand for high-precision etching is becoming more and more urgent. Hexafluorobutadiene (C₄F₆), as an advanced etching gas, plays an important role in the semiconductor etching process.1. Application advantages( 1 ) High etching selectivity : In semiconductor manufacturing, hexafluorobutadiene can etch different material layers with high precision. For example, when etching materials such as silicon dioxide and silicon nitride, it can selectively remove the target material with minimal damage to other materials. This is because the molecular structure of hexafluorobutadiene enables it to precisely interact with the chemical bonds of the target material during the etching reaction.( 2 ) Fine etching capability : Hexafluorobutadiene performs well in etching circuit patterns at the submicron and nanometer levels. It can achieve very fine line etching, which helps to improve the integration of chips. For example, in chip manufacturing with a process of 10 nanometers and below, hexafluorobutadiene can etch complex circuit structures to meet the manufacturing requirements of high-performance chips.       2. Economic and environmental benefits( 1 ) Reduce production costs : The use of hexafluorobutadiene can reduce side reactions during the etching process, thereby improving etching efficiency. This means that in large-scale production, the etching process time can be shortened and the operating cost of the equipment can be reduced. For example, compared with traditional etching gases, the use of hexafluorobutadiene can increase the production capacity of etching equipment by about 30%, which correspondingly reduces the etching cost per chip.( 2 ) Good environmental performance : Hexafluorobutadiene produces relatively few decomposition products during the etching process and has less pollution to the environment. Its global warming potential (GWP) is low and meets environmental protection requirements. In the context of increasingly stringent environmental regulations, the use of hexafluorobutadiene can help semiconductor companies meet environmental standards and reduce greenhouse gas emissions.        3. Challenges and solutions( 1 ) Supply stability : The production technology of hexafluorobutadiene is relatively complex, and there are currently few manufacturers in the world that can produce it on a large scale. Jiayuan is keenly aware of this, keeps up with market trends, and is more strict with itself in terms of production quality and production safety, so as to ensure stable supply of products while also guaranteeing product quality.( 2 ) Safe storage and transportation : Hexafluorobutadiene is a high-pressure gas and is somewhat dangerous. Safety regulations must be strictly followed during storage and transportation. For example, special high-pressure gas containers must be used and transportation vehicles must meet safety standards. At the same time, companies need to provide safety training to relevant personnel to reduce safety risks.We have a professional sales team and technical service team to provide customers with high-quality fluorine chemical products, good technical support, and a sound after-sales service system. Based on the principle of "customer first, integrity first", we provide high-quality products and services and go hand in hand with customers.

Magnesium fluoride coating: multi-field applications and excellent performance

The main purpose of coating is to reduce reflections and to improve the transmittance of the lens and the quality of the image. In modern lens manufacturing processes, the lens must be coated. Lens coating is based on the principle of optical interference. A layer of substance (usually fluoride) with a thickness of one-quarter wavelength is coated on the surface of the lens to minimize the reflection of the lens to the color light of this wavelength. One layer of film only works on one color light, while multi-layer coating can work on multiple colors of light. Multi-layer coating usually uses different materials to repeatedly coat different thicknesses of film layers on the surface of the lens. Multi-layer coating can greatly improve the transmittance of the lens. For example, the reflectivity of each surface of an uncoated lens is 5%, which is reduced to 2% after single-layer coating, and can be reduced to 0.2% with multi-layer coating. This can greatly reduce the diffuse reflection between the lenses of the lens, thereby improving the contrast and sharpness of the image.Magnesium fluoride coatingMagnesium fluoride is a kind of coating material. Magnesium fluoride crystal (MgF 2 ) belongs to the tetragonal system, with a melting point of 1255°C, high hardness, good mechanical properties, stable chemical properties, and not easy to deliquesce and corrode. Its main feature in optical properties is that it has a high transmittance in the vacuum ultraviolet band (the transmittance at 170nm is still above 80%). It is widely used in optical fiber communications, military fields and various optical components.Application of magnesium fluoride coatingThe main application of magnesium fluoride coating is coating on the surface of ordinary tempered glass, thereby improving the light transmittance of the tempered glass surface and achieving easy cleaning function, while also extending the life of the glass. AR coated glass can currently be mainly used in solar cell components, solar thermal, construction, automotive glass and other fields.Preparation of magnesium fluoride coatingMagnesium fluoride coating uses evaporation method, which is called evaporation coating by heating and evaporating a certain substance to make it deposit on the solid surface. This method was first proposed by Faraday in 1857 and has become one of the commonly used coating technologies in modern times. Evaporating substances such as metals, compounds, etc. are placed in a crucible or hung on a hot wire as an evaporation source, and the substrates to be plated such as metals, ceramics, plastics, etc. are placed in front of the crucible. After the system is evacuated to a high vacuum, the crucible is heated to evaporate the substance in it, and the atoms or molecules of the evaporated substance are deposited on the surface of the substrate in a condensed manner. The film thickness can range from hundreds of angstroms to several microns. The film thickness is determined by the evaporation rate and time of the evaporation source (or by the charge amount), and is related to the distance between the source and the substrate. For large-area coating, a rotating substrate or multiple evaporation sources are often used to ensure the uniformity of the film thickness. The distance from the evaporation source to the substrate should be less than the mean free path of the vapor molecules in the residual gas to prevent chemical reactions caused by collisions between the vapor molecules and the residual gas molecules. The high-quality glass is processed on one or both sides to have a lower reflectance than ordinary glass, and the reflectivity of light is reduced to below 1%. In the visible light range, the single-sided reflectivity of ordinary glass is about 4%, and the total spectral reflectivity is about 8%.Jiayuan has layout in both the upstream and downstream of the fluorine chemical industry chain, forming a complete fluorine chemical industry chain. At the same time, Jiayuan is also constantly conducting technological research and development and innovation, and has stronger competitiveness and market position in the production, sales and research and development of magnesium fluoride products.

Solid-state sodium-ion batteries: the bright new star of next-generation energy storage technology

Recently, solid-state sodium-ion battery technology has once again attracted widespread attention in the industry. This new battery technology is regarded as a shining star in the next generation of energy storage technology due to its high safety, high energy density and abundant raw material resources.The working principle of solid-state sodium-ion batteries is similar to that of traditional sodium-ion batteries, but the key is that they use solid electrolytes instead of traditional liquid electrolytes. During the charging process, sodium ions (Na+) are released from the positive electrode material, migrate to the negative electrode through the solid electrolyte, and are embedded in the negative electrode. At the same time, electrons flow from the positive electrode to the negative electrode through an external circuit to maintain charge balance. The discharge process is the opposite. Sodium ions are released from the negative electrode, migrate back to the positive electrode through the solid electrolyte, and electrons flow from the negative electrode to the positive electrode through an external circuit to form an electric current. This unique mechanism makes solid-state sodium-ion batteries excel in energy density and safety.Solid-state sodium-ion batteries have significant advantages over traditional lithium-ion batteries. First, the reserves of sodium in the earth's crust are abundant, far exceeding lithium, so the raw material cost of solid-state sodium-ion batteries is relatively low. This helps to reduce the manufacturing cost of batteries and promote their commercial application. Secondly, solid-state electrolytes have high mechanical strength and chemical stability, and are not prone to safety problems such as leakage and combustion, so solid-state sodium-ion batteries have higher safety. In addition, solid-state electrolytes can inhibit the growth of sodium dendrites, thereby improving the cycle stability and life of the battery.In recent years, solid-state sodium-ion battery technology has made significant progress. Many scientific research institutions and enterprises at home and abroad have invested in research and development, committed to improving the ionic conductivity, chemical stability and compatibility of solid electrolytes with electrodes. At the same time, by optimizing electrode materials and battery structures, the energy density and cycle performance of solid-state sodium-ion batteries have been further improved.It is worth mentioning that solid-state sodium-ion batteries have shown broad application prospects in many fields. In the field of electric vehicles, the high energy density and long life of solid-state sodium-ion batteries help to improve the range and service life of electric vehicles. In home and industrial energy storage systems, solid-state sodium-ion batteries can be used as battery components to store and supply electricity to meet various electricity needs. In addition, solid-state sodium-ion batteries can also be used in renewable energy systems such as solar and wind power to store excess electricity and provide reliable energy support for unstable power grids.However, the development of solid-state sodium-ion battery technology still faces some challenges. First, the cost of solid-state electrolytes is relatively high, which limits the commercial application of solid-state sodium-ion batteries. Second, the interface stability between solid-state electrolytes and electrodes still needs to be further improved to optimize the electrochemical performance of the battery. In addition, the production process and technical maturity of solid-state sodium-ion batteries also need to be further improved.Nevertheless, as a bright new star of the next generation of energy storage technology, the development prospects of solid-state sodium-ion batteries are still worth looking forward to. With the continuous advancement of technology and the gradual reduction of costs, solid-state sodium-ion batteries are expected to play an important role in electric vehicles, energy storage systems and renewable energy, and contribute more to the sustainable development of human society.Jiayuan produces sodium fluoride stably . Sodium fluoride can provide a source of sodium ions, which play a key role in the battery charging and discharging process. In addition, the ionic properties of sodium fluoride enable it to form stable compounds with other materials, thereby optimizing the electrochemical performance of solid-state sodium ion batteries. The development of sodium fluoride and solid-state sodium ions complement each other and promote the further expansion of Jiayuan's strategic map.

It is also used in the production of intermediates for anticancer drugs, pesticides, dyes and other industrial products. It is used in the production of many inorganic compounds such as potassium hydrogen fluoride, potassium fluoroaluminate, titanium tetrafluoride, fluoroaluminum mullite, etc. It is also used in glass engraving, food preservation, electroplating, welding flux, etc. It is used in medicine to produce norfloxacin. High-purity potassium fluoride is used in the Stockbarger method to produce single crystals.Physical and chemical properties:White cubic deliquescent powder with a distinct salty taste. Relative density 2.481, melting point 858℃, boiling point 1505℃. Soluble in water. Potassium fluoride has two hydrates, KF·2H2O and KF·4H2O. Potassium fluoride dihydrate is crystallized in an aqueous solution at a temperature below 40℃, is stable at room temperature, and loses crystal water above 40℃. Anhydrous potassium fluoride can only remove a few percent of water by long-term drying at 250-300℃, and cannot be pyrolyzed at a high temperature of 1000℃. Potassium fluoride aqueous solution is alkaline and can corrode glass. Molten potassium fluoride is highly active and can corrode glass. Production methodNeutralization method . Prepared with potassium hydroxide and hydrogen fluoride as raw materials. Put solid potassium hydroxide of superior grade or above into a reactor containing an equal amount of water, and then pass anhydrous hydrogen fluoride from the bottom of the reactor for neutralization. When pH=7-8, stop passing anhydrous hydrogen fluoride, let the reaction liquid settle for 24 hours, and the clear liquid is vacuum evaporated, crystallized, transitionally separated, and dried to obtain the product.The reaction formula is as follows:HF+KOH→KF+H2OThe reaction solution can also be mixed with a surfactant, and after spray drying, a potassium fluoride product with high bulk density, high specific surface area, low hygroscopicity, high activity and reduced usage can be obtained. Packaging, storage and transportationUse polypropylene woven bags lined with two layers of polyethylene plastic bags or polyethylene plastic barrels. The net weight of the enzyme belt is 10kg or 25kg, and the net weight of each barrel is 50kg. It should be stored in a ventilated, cool and dry warehouse.
