Product description

tuProduct introduction:

Fluorspar is also called Fluorite. Calcium fluoride (CaF2) is a mineral, isoaxial crystal system, whose main component is calcium fluoride (CaF2). With many impurities, Ca is often replaced by Y and Ce and other rare earth elements. In addition, it also contains a small amount of Fe2O3, SiO2 and trace amounts of Cl, O3 and He.

Natural fluorspar is often bright color, some can have fluorescence. Fluorspar comes from volcanic magma. In the process of magma cooling down, the aqueous solution by magma isolated gas contains many substances with mainly fluoride. In the process of solution along the fracture, the temperature is reduced, the pressure is reduced, air fluoride ion in aqueous solution combined with calcium ions in the surrounding rocks to form calcium fluoride which form the fluorspar by cooling crystallization.
