Aluminum Fluoride
Chemical formula: AlF3 Molecular weight: 83.98 Specifications: implementation of national standard GB4292-2007
Physical Properties: anhydrous aluminum fluoride for the sand-like powder, specific gravity 2.882 ~ 3.13g/cm3, capacity of 1.3 ~ 1.6g/cm3, angle of repose of about 30 °, flow coefficient is less than 60s/kg. Insoluble in water, acid and alkali solutions, are very stable wet white powder of aluminum fluoride, Department of needle crystal crystal, specific gravity is about 2.882 ~ 3.13g/cm3, sublimation temperature of 1272 ° C, slightly soluble in water, hydrofluoric acid solution in the greater solubility; anhydrous aluminum fluoride, the chemical properties of extremely stable, but at high temperatures, with some aluminum fluoride crystal water will be hydrolyzed to Al2O3, and release HF gas.
Usage: mainly used to reduce the production of aluminum melting point and improve the conductivity of the electrolyte, is also used as the outer layer of ceramic glaze and porcelain enamel glaze flux and flux of non-ferrous metals.
Packaging: 25 kg plastic film bag lined plastic woven bag or paper bag packaging laminating.
