Description

Aluminum Fluoride CAS NO 7784-18-1 is an inorganic compound primarily used as a flux in the aluminum smelting industry. Its primary value lies in lowering the melting point and increasing the conductivity of the electrolytic bath, which significantly improves production efficiency and reduces energy consumption. This high-purity chemical is essential for manufacturers in the aluminum production, ceramics, and specialty glass sectors who require consistent quality and reliable supply to maintain their operational benchmarks.

Application

• Primary fluxing agent in the Hall-Héroult process for aluminum production.
• Additive in the manufacture of specialty opalescent and milky glass.
• Catalyst and fluorinating agent in organic synthesis reactions.
• Raw material for the production of synthetic cryolite (Na3AlF6).
• Component in the production of ceramic glazes and enamels.
• Used in the formulation of certain welding fluxes and brazing agents.
• Intermediate in the manufacture of other aluminum salts and fluoride compounds.
