Fluorite is chemically composed of calcium fluoride and is a mineral with a lower melting point (melting point 1270-1350 ° C). Issued at the cathode-ray fluorescence, a light-heat some variants, the phosphors made sunlight. There are few colorless fluorites, often in yellow, gray, green, blue, purple, red, brown, black and other beautiful colors.

Due to its low melting point melt temperature, it is mainly used as the metallurgical smelting steel flux practiced. It forms a eutectic mixture with the slag, and has high activity and fluidity. It can react well with harmful impurities such as sulfur and phosphorus in the charge to make the slag and metal easily separate, and it functions as desulfurization and dephosphorization. Used in alkaline open hearth furnaces, alkaline oxidation furnaces and electric furnace steelmaking.
It is mainly used in the chemical industry to produce hydrofluoric acid and its derivatives. Fluorite half the world production system as hydrofluoric acid, for preparation of cryolite for aluminum in the refining industry. A part is used to make carbon fluoride. Fluorinated carbon is odorless, non-toxic, inert, and non-corrosive. It can be used as a coating, lubricant, preservative, detergent, etc., and its output is half used in aviation cleaners. When making plastics, PTFE made of fluoride is known as “Plastic King†and it is not brittle in liquid air. The boiling water is not soft and can be used in the temperature range of -263°C to +260°C. Corrosion resistance and chemical stability are more than glass, ceramics, stainless steel, gold, platinum, etc., and are widely used. Fluorite is also an important ingredient in the glass, ceramic and diabase casting industries. Colorless and transparent can also be used as optical instruments, bright colors can be used as art crafts.
When the high-purity fluorite contains a rare earth element such as Nd to a certain content, it can also be used as a laser material. Large fluorite crystals can be used as spectrographs, smaller crystals can be used as mirrors on microscopes, and lenses and prisms that eliminate chromatic aberrations and spherical aberrations can also be fabricated.
