Calciumfluoride

CAS: 7789-75-5
Molecular Formula: CaF2
Molecular Weight: 78.08
Product description:With a green or purple. When heated. Density of 3.18 g/cm 3, melting point 1402 ℃, boiling point 2497 ℃, the refractive index of 1.434. Low toxicity. Very difficult to soluble in water. Soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, insoluble in acetone. Soluble in aluminum salt and iron salt solution to form complex, generate hydrofluoric acid and hot concentrated sulfuric acid. Calcium fluoride with concentrated sulfuric acid reaction can be obtained in the castle hydrogen fluoride. With a variety of metal oxide eutectic formed.Produce hydrofluoric acid. Hydrofluoric acid is through acid grade fluorspar (fluorspar ore concentrate) react with sulfuric acid in the furnace or jar and produced, anhydrous hydrofluoric acid and hydrofluoric acid water, they are all a colorless liquid, volatile, have the exciting taste of intense and strong corrosion resistance. It is in the production of various organic and inorganic fluoride and fluorine element of key raw materials.
