Physical properties:
Cryolite is a kind of complex compound or double salt. Caused by impurity, the appearance can be white, gray ,yellow powder or crystalline particles. It's melting point is 1025ºC, stacking density is 0.6-1.0g/L, true density is 2.95-3.05g/cm 3 , heat of formation is 225KJ, specific gravity is 2.75-3.00g/cm 3 , heat of fusion is 107KJ. Slightly solubte in water.
Applications
Aluminium- metallurgy: as component of fluxing agents, protective and refining salts;
