· K3AlF6

K3AlF6 (potassium aluminum fluoride) is an inorganic fluoride compound classified as a salt rather than a traditional metallic alloy, despite its database categorization. It functions primarily as a flux material and chemical intermediate in aluminum processing and specialty glass manufacturing, where it lowers melting temperatures and improves flow characteristics. This compound is valued in cryolite-based metallurgical processes and as a precursor in fluorochemical production, offering advantages over pure cryolite in specific high-temperature applications where aluminum reduction or glass fusion occurs.
