Description

Ammonium Hexafluoroaluminate is an inorganic salt primarily used as a fluxing agent in metallurgical and ceramic applications. Its value lies in its ability to lower melting points and promote the fusion of materials, which is critical for efficient industrial processing. This compound is essential for manufacturers in the aluminum production, glass, and ceramic industries seeking to improve product quality and process efficiency.

Application

• Primary fluxing agent in the electrolytic production of aluminum.
• Flux and opacifier in the manufacture of specialty glasses and enamels.
• Additive in ceramic glazes to modify melting characteristics and surface finish.
• Component in brazing and soldering fluxes for non-ferrous metals.
• Used in the synthesis of other complex fluoride salts and aluminum compounds.
• Research and development chemical in material science for new alloy and ceramic formulations.
