Aluminum fluoride
Molecular formula: AlF3 Molecular weight : 83.98
Uses: Mainly used for production, in order to reduce the Melting point and improve the conductivity of electrolyte. as the fermentation inhibitor in Alcohol production. Also used for ceramic glaze and enamel glaze flux and glaze medicine components. Also can be used as smelting non-ferrous metal flux.
Property: and liquid ammonia or concentrated sulfuric acid were heating, or person with potassium hydroxide eutectic melting were no response. Don't be hydrogen reduction, strong heat decomposition but sublimation, Property very stable. Heated to 300-400 ℃ can be parted into the vapor and decomposed into hydrogen fluoride and alumina.
