Description

Aluminium Fluoride CAS NO 17949-86-9 is an inorganic compound primarily used as a flux in the aluminum smelting industry. Its core 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 seeking reliable, consistent performance.

Application

• Primary fluxing agent in the Hall-Héroult process for aluminum production.
• Additive in the manufacture of opalescent and specialty glass to enhance durability and optical properties.
• Catalyst and fluorinating agent in organic synthesis and the production of fluorinated compounds.
• Key raw material in the ceramics industry for producing enamels and welding fluxes.
• Used in the formulation of certain electrolytes for lithium-ion batteries.
• Component in the synthesis of synthetic cryolite (Na3AlF6).
