Fluorspar | Canada Commons

Fluorspar. Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as Fluorite.

Fluorspar

At higher temperatures the fluorine becomes volatile and is released as a poisonous gas. This happens as O2 combines with CaF2 to produce CaO and F2 gas. Even if the gas can be tolerated, the material slowly decomposes to evolve the fluorine gas, and thus is troublesome for use in glazes because of the blistering problems. If fluorspar is being ...
