Sodium Fluoroaluminate

Sodium Fluoroaluminate

Properties: White free flowing powder, slightly soluble in water.
Application: 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.

   Cryolite(Sodium Fluoroaluminate) is colorless monoclinic crystal, the appearance is similar to cube, the pure product is colorless, often grayish white, light yellow, light red, black due to impurities. It is often an inseparable dense block with a glossy, translucent, white streak and a glassy finish. The relative density is 2.9 to 3.0, and the melting point is 1000 °C. It is easy to absorb water and damp. It is soluble in water, and the aqueous solution is acidic. In case of sulfuric acid, it can liberate highly toxic hydrogen fluoride gas.
