Note: AF-0 AF-1 is the standard of dry aluminum fluoride (anhydrous aluminum fluoride), AF-2 AF-3 is the standard of wet aluminum fluoride.
Property: Aluminum fluoride is colorless or white crystal, relative density (water = 1) 1.91g/cm3 , melting point 1040°C, boiling point 1537°C, insoluble in water, acid, alkali, insoluble in most organic solvents, heated to 300-400°C can be partially decomposed by water vapor into hydrogen fluoride and aluminum fluoride.
Uses: It is used to reduce the melting temperature of electrolyte and improve conductivity in aluminum electrolysis industry, used as flux for non-ferrous metals, flux for ceramic glaze and enamel glaze, and inhibitor of secondary fermentation in essential oil production.
Packaging: Film-coated plastic woven bag, lined with plastic film bag, net weight of each bag 25Kg, 50Kg, 1000Kg (or packaged according to customer requirements)
