· JVASP-101479· KNa2AlF6

KNa₂AlF₆ is an inorganic fluoride compound, specifically a cryolite-type material (potassium sodium aluminum fluoride), belonging to the family of complex metal fluorides. This compound is primarily used as a flux and electrolyte material in aluminum smelting and metallurgical processing, where it lowers the melting point of alumina and improves electrical conductivity in the Hall-Héroult process. Its fluoride composition makes it valuable in high-temperature molten-salt applications where thermal stability and ionic conductivity are critical, though it has largely been supplemented by synthetic cryolite (Na₃AlF₆) in modern industrial practice.

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.
