Na3 Al1 F6
metal· Na3 Al1 F6
Na3AlF6, commonly known as cryolite, is an ionic compound and naturally occurring mineral that serves as a flux and electrolyte in industrial processes. This material is primarily valued in the aluminum smelting industry, where it lowers the melting point of alumina and improves electrical conductivity in Hall-Héroult electrolytic cells; engineers select it because it dramatically reduces energy consumption compared to smelting pure alumina alone. Beyond primary aluminum production, cryolite finds applications in specialized glass manufacturing, welding fluxes, and ceramic production where its fluxing properties and thermal stability are advantageous.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
