Physical propertiesCryolite 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.


ApplicationsAluminium- metallurgy: as component of fluxing agents, protective and refining saltsProduction of abrasives: as active filler in resinbonded abrasives for metal treatmentProduction of enamel, glazing frits and glass: as flux and opacifying agentProduction of soldering agent: as component for fluxing agentsProduction of welding agents: as component of welding rod coatings and welding powdersBlasting and pyrotechnics: for fireworksMetal surface treatment: as component in pickling pastes for stainless steel.Packing: In 25kgs PP bags, Lined with high-pressure plastic film, or according to customer's requirements.
