Aluminum fluoride

CAS No.: 7784-18-1

MF: ALF3

EINECS No.: 232-051-1

Purity: >=92.5%

Grade Standard: Agriculture Grade

Appearance: Aluminum fluoride is available as white powder or crystal with density of 3.00g/cm3, melting point is 1040°C, boiling point is 1272°C. It is slightly soluble in water, hardly soluble in acid and alkali solution, insoluble in most organic solvents, also insoluble in hydrofluoric acid and liquefied hydrogen fluoride. The property of anhydrous aluminum fluoride is very stable. It doesn’t react with liquid ammonia or concentrated sulfuric acid by heating to fuming and doesn’t changeable when co-melted with potassium hydroxide. It is not reduced by hydrogen and doesn’t decompose through heating but it may sublime. It can be hydrolyzed partly to hydrogen fluoride and aluminum oxide in the vapour of 300-400°C.

Application

Aluminum fluoride is used as auxiliary ingredient of electrolyte during the production of electrolytic aluminum to decrease the melting point and increase the conductivity of electrolyte. Also, it is a flux for non-ferrous metal, as a zymotic inhibitor in the alcohol and essential oil production and as a fusing assistant for ceramic, enamel and the component of glaze.
