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 1025℃, stacking density is 0.6-1.0g/L, true density is 2.95-3.05g/cm3, heat of formation is 225KJ, specific gravity is 2.75-3.00g/cm3, heat of fusion is 107KJ. Slightly solubte in water.
Applications
Aluminium- metallurgy: as component of fluxing agents, protective and refining salts；
Production of abrasives: as active filler in resinbonded abrasives for metal treatment；
Production of enamel, glazing frits and glass: as flux and opacifying agent；
Production of soldering agent: as component for fluxing agents；
Production of welding agents: as component of welding rod coatings and welding powders；
Blasting and pyrotechnics: for fireworks；
Metal surface treatment: as component in pickling pastes for stainless steel.
Packing：In 50kgs PP bags, Lined with high-pressure plastic film, or according to contract’s requirements.
