Synthetic Cryolite
We are manufacturers Guaranteed quality, low price It is a white crystalline powder or a sandy size granularity as well.
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 Quality Index:SPECIFICATION (GB/T4291-2007) | CHEMICAL COMPOSITION (%) | CH-0 | CH-1 | CM-0 | CM-1 |
