Research on properties and development of magnesium fluoride

As colorless crystal or powder, magnesium fluoride is an important inorganic chemical raw material. It is used as additive for electrolytic aluminum, flux for smelting magnesium metal, coating agent for titanium pigment, fluorescent material for cathode ray screen, etc. At the same time, it is also a colorless and transparent infrared optical material with wide transmission range and high transmittance, which can be used to make optical prism, lens and window element in infrared optical system.Due to the different requirements for the quality of magnesium fluoride in various fields, the preparation methods are also different. The raw materials for industrial production of magnesium fluoride mainly come from magnesite and salt lake brine, which are suitable for large-scale industrial production, while the raw materials for the laboratory preparation of high-quality magnesium fluoride come from finished magnesium salt.At present, the research direction of magnesium fluoride preparation mainly includes the following aspects:First, on the basis of ensuring a certain purity of magnesium fluoride, further improve the production process and reduce the production cost;Secondly, the finished magnesium fluoride particles should have better dispersion and more uniform particle size distribution to ensure good optical properties;In addition, some new fields, such as magnesium fluoride nano-antibiotic film and magnesium fluoride nanotubes, have also been gradually developed and utilized. Research on the properties and development of magnesium fluoride magnesium fluoride is colorless crystal or powder, and is an important inorganic chemical raw material. Used as additive for electrolytic aluminum, flux for smelting magnesium, titanium In the production of aluminum, aluminum fluoride is used as an electrolytic bath component to reduce the melting point and improve the conductivity of the electrolyte. Used to inhibit fermentation in alcohol production Magnesium fluoride has a low refractive index and can form a wide band gap with high refractive index materials. It can be used as a low refractive index material in photonic crystals Mix magnesium fluoride powder and high-purity PbF2 powder evenly, load the crucible clamp, put the crucible clamp on the crucible base, install the heating body, and adjust the bottom of the crucibleAs colorless crystal or powder, magnesium fluoride is an important inorganic chemical raw material.

Introduction of magnesium oxide in the field of new inorganic magnesium materials

In recent years, the term "inorganic magnesium salt new material" has hit the hot spot several times. The group of inorganic magnesium salt new material mainly includes magnesium oxide, magnesium carbonate, magnesium sulfate, magnesium hydroxide and magnesium product compounds. The enterprises that mainly produce magnesium compounds are distributed in chemical, steel, non-ferrous metals, light industry, food, electronics and other industries.Inorganic magnesium salt compounds include hundreds of products, the most important of which are magnesium oxide, magnesium hydroxide, magnesium carbonate and other major products. These products can be divided into ore, brine process and chemical by-products according to the type of raw material source. The production of magnesium compounds in China has a wide range of raw materials and a variety of process routes. The coexistence of multiple technical routes and product types in the magnesium compound industry has taken shape.The development direction of refined products: magnesium compound products have special characteristics, many varieties and specifications, and the market space for developing refined products is broad. Rubber, ceramics and other industries need industrial light magnesium oxide; Neoprene rubber, fluororubber, adhesives and sealing materials need various kinds of active magnesium oxide; Silicon steel grade magnesium oxide required for steel plate making; The electronic industry, national defense industry and aviation industry need high-purity magnesium oxide; Pharmaceutical grade magnesium oxide required for pharmaceuticals; Reagent-grade magnesium oxide is required for analysis.

Magnesium oxide plays an important role in environmental protection

Magnesium oxide is an inorganic salt material, commonly used as rubber additive and magnesium compound magnesium ion supplement. At the same time, magnesium oxide plays an important role in environmental protection, such as water treatment, gas desulfurization, soil treatment and other related fields. Magnesium oxide plays a certain role in environmental pollution and treatment. The adsorption process of magnesium oxide plays a very important role in the play of these roles. The application of magnesium oxide is widely used in the treatment of waste gas. Magnesium oxide adsorption can effectively adsorb waste gas. It can be handled effectively. And the cost is low.

Early reminder of dichloroethane market (20220324)

Yesterday, the domestic dichloroethane market price was stable and the market transaction atmosphere was general. The arrival of goods at the end of the month is expected to have a certain impact on local market prices. The bulk water supply price in Jiangyin area is around 5200 yuan/ton, and the merchants have less inventory, and have no intention of stocking under the high price recently, so the market is in a high wait-and-see mood.
