Synthetic Cryolite
【Molecular formula】: Na3AlF6
【Molecular weight】: 209.5
【CAS】: 15096-52-3
【Execute standard】: GB/T4291-2007
【HS CODE】:2826.3000
【Properties】:still named sodium fluoaluminate. It is a white crystalline powder or a sandy size granularity as well. Melting point about 1000ºC. It is insoluble in anhydrous hydrogen fluoride, but slightly in water.
【Uses】: It is mainly used as a flux in the aluminium smelting by fused salt electrolysis;also an opalizer in the manufacture of enamel;an opacifier and auxiliary solvent of glass and enamel;an insecticide of crops;a flux in aluminium alloy casting;and in the production of ferrous alloy and effervescing steel.
【Packing】: 25kg/woven bags with inner plastic lining, or as the request of our customer
