Properties

It is used in the manufacture of organic or inorganic fluoride, such as fluorocarbon, sodium fluoride, aluminum fluoride, uranium hexafluoride and cryolite. It is also used for pickling of stainless steel and non-ferrous metals, engraving and lettering of glass instrument scales, glassware and mirrors, polishing of glassware, treatment of frosted bulbs and general bulbs, silicon removal and purification of metal graphite emulsion, sand removal of metal castings, removal of graphite ash, and manufacturing of Semiconductors (germanium and silicon). It is also used as a catalyst for dye synthesis and other organic synthesis. It is also used in electroplating, reagent, fermentation, ceramic treatment and the manufacture of fluororesin and flame retardant.
