application

1. In the ceramic industry, it is used to reduce the temperature of the kiln and improve the resistance to thermal shock, abrasion and acid corrosion.

2. Used as a flux for metal welding together with other fluorides, chlorides and borates.

3. It is the basic component of fluorine electrolytic cell electrolyte. In high-temperature storage batteries in a molten state as the electrolyte component.

4. A large number of fluxes and brazing fluxes used in aluminum and magnesium alloys are also used as additives to improve electrical efficiency in the electrolytic aluminum industry.
