 APPLICATIONS

– its main use is in the production of aluminum where it forms the electrolytic bath. It has also found industrial use in the production of insecticides, metals and alloys, glass and enamels, welding rods, resins, explosives and fireworks, and polishes. The toxic effects of cryolite are largely due to its content of aluminum and fluoride. Thus, its toxic effects, if not known, have to be based on known adverse effects of aluminum and fluoride.

 

Aluminium- metallurgy:

- as component of fluxing agents, protective and refining salts

Production of abrasives:

- as active filler in resinbonded abrasives for metal treatment

Production of enamel, glazing frits and glass:

- as flux and opacifying agent

Production of soldering agent:

- as component for fluxing agents

Production of welding agents:

as component of welding rod coatings and welding powders

Blasting and pyrotechnics: – for fireworks

Metal surface treatment: – as component in pickling pastes for stainless steel
