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;
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 25kgs PP bags, Lined with high-pressure plastic film, or according to customer's requirements.

 

Application:
 

1. Mainly used as flux for aluminum electrolysis;

2. It is also used as wear-resistant additive for grinding products, which can effectively improve the abrasion resistance, cutting and cutting force of grinding wheel, and extend the service life and storage time of grinding wheel.

3. Ferroalloy and fluidized steel flux, nonferrous metal flux, casting deoxidizer, olefin polymerization catalyst, as well as glass anti-reflection coating, enamel emulsifier, glass emulsifier, welding flux, ceramic filler, pesticide insecticide and other industries.
