Fluorite powder contains halogen element fluorine, which can reduce the melting point of refractory, promote slag flow, separate slag from metal, desulfurize and dephosphorize during smelting, and enhance the ductility and tensile strength of metal.

2. The main chemical component of fluorite slag is calcium fluoride, which is a transparent rock with many colors such as white, red, blue, green and purple. Fluorite existing in nature is mostly mixed with silica, calcium carbonate, iron oxide and alumina. Its melting point is 1230 degrees, and it has strong fluxing effect, so it is the raw material of fluxing agent in glaze.
