BRIEF DESCRIPTION
Calcium fluoride is the main component of fluorspar, or fluorite, and is a colorless cubic crystal or white powder. Glows when heated. It is soluble in concentrated inorganic acids and decomposes to release hydrogen fluoride. It is slightly soluble in dilute inorganic acids and almost insoluble in water. Relative density 3.18. Melting point 1402℃. Boiling point 2500℃. Low toxicity.

CHEMICAL PROPERTIES
Calcium fluoride has a relative density of 3.18, a melting point of 1423°C, and a boiling point of about 2500°C. The solubility in water is extremely small. At 18°C, only 0.0016g is dissolved in 100g of water. It is insoluble in acetone, but soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solutions. It has almost no effect on dilute strong acids and hot concentrated sulfuric acid. The reaction generates hydrofluoric acid, which forms a complex when dissolved in aluminum salt and iron salt (Fe3+) solutions.
