Calcium fluoride Usage And Synthesis

Chemical Properties

Calcium fluoride is the main ingredient of fluorspar or fluorite, the chemical formula is CaF2, it is colorless cubic crystal or white powder. The relative density is 3.18, the melting point is 1423℃, boiling point is about 2500 ℃. The solubility in water is minimal , 100g water can dissolve only 0.0016g at 18 ℃, it is insoluble in acetone, but soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, and it can not react with dilute acid, but can react with hot concentrated sulfuric acid and generate hydrofluoric acid, it can form a complex when dissolves in aluminum and iron salts (Fe3 +) solution. Natural calcium fluoride is mineral fluorite or fluorspar, often shows gray, yellow, green, purple and other colors, sometimes it is colorless, transparent, shiny glass, brittle, and the relative density is 3.01~3.25, it has significant phenomenon of fluorescence. It can be used as the source of fluorine and the material to make hydrofluoric acid system, fluoride; and it can also be used in terms of the manufacture of glass, enamel, glaze. Fluorite is mainly used as a flux in metallurgy, the very pure fluorspar can be used to make specialty lenses. Water when contains (1~1.5) × 10-6 calcium fluoride can prevent dental problems. In addition, it can be used in smelting iron and steel, chemicals, glass, ceramics manufacturing. Pure product can be used for catalyst of dehydration, dehydrogenation. By the effect of soluble calcium salts (calcium carbonate or calcium hydroxide) and sodium fluoride or hydrofluoric acid, ammonium fluoride, calcium fluoride can be obtained.

Uses

Industry	Application	Role/benefit
Chemical manufacture	Production of hydrofluoric acid and fluoride	Raw material/source of fluoride
Chemical manufacture	Production of fluorine fine chemicals and synthetic cryolite	Raw material/source of fluoride
Architectural material	Production of glass	Fluxing agent/promote the melting of raw materials
	Production of cement	Mineralization agent
	Production of ceramic glaze	Fluxes and coloring aids
Metallurgy	Iron and steel smelting, ferroalloy production,etc.	Fluxing agent/reduce the melting point of refractory substances
Medicine	Treatment, control, prevention, & improvement of allergic reactions	Promoting new bone formation
Thermal imaging systems, spectroscopy, telescopes and excimer lasers	Manufacture of optical components, such as windows and lenses	Raw material/broad range of transmission light frequencies; low refractive index; high thermo stability
Others	Production of welding agents	Important components in coatings of welding rods and welding powders
	Dehydration and dehydrogenation reaction	Catalyst/accelerate the process of reaction
	Manufacture of brake lining	Additive/helps reduce abrasion caused by high heat and friction

Production method

The fluorite deposits which have been found in china, are main used the mine using underground mining method, or shallow open-pit mining, and underground deep mining, for ore body most tilt vein, the extending is also large. Mining method is based in shallow hole Shrinkage Method based. Mining process sees "phosphate rock." Beneficiation methods have two types generally, the one is raw ore can become qualified ore concentrate by handling select, the second is hand-selected lean ore and tailings.

Chemical Properties

White Powder

Uses

Fluorspar is the main primary source of fluorine and its Compounds. In ferrous metallurgy it is used as a flux to increase the fluidity of the slag. The steel industry is the largest consumer; the chemical industry, second and glass and ceramics, third. Synthetic fluorspar is used in the optical industry (transmits u.v. rays), and pure calcium fluoride is used as catalyst in dehydration and dehydrogenations. Used to fluoridate drinking water.

General Description

Odorless gray powder or granules. Sinks in water.

Reactivity Profile

Calcium fluoride has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

Little acute toxicity
