Preparation of Calcium fluoride: this chemical can be prepared by treating Calcium carbonate with Hydrofluoric acid:
CaCO3 + 2 HF → CaF2 + CO2 + H2O
Uses of Calcium fluoride: this chemical is commonly used as a window material for both infrared and ultraviolet wavelengths in the laboratory. This use has largely been superseded by newer glasses and computer aided design. Moreover, Uranium-doped Calcium fluoride was the second type of solid state laser invented. It is also used as a flux for melting and liquid processing of iron, steel and their composites. Furthermore, it can react with concentrated sulfuric acid to produce Hydrogen fluoride:
CaF2(s) + H2SO4 → CaSO4(solid) + 2 HF(g)
When you are using this chemical, please be cautious about it as the following: it is irritating to eyes, respiratory system and skin. In case of contact with eyes, please rinse immediately with plenty of water and seek medical advice. And you should wear suitable protective clothing, gloves and eye/face protection.
