Product name: Sodium Cryolite; Synthesis Cryolite; Artificial Cryolite; Sodium Hexafluoroaluminate

CAS No :13755-53-6

Formula : Na₃AlF₆ 

Property:

Cryolite is a mineral, white monoclinic crystals, slightly soluble in water, the aqueous solution is acidic, and often appears grayish white, light yellow, light red or black due to impurities. 

Application:

1. Aluminium-metallurgy: as component of fluxing agents, it can effectively help remove hydrogen and oxidation slag in liquid aluminum, improve the purity of aluminum and product quality.
?2. High temperature lubricant: crolyte is widely used in the manufacture of high temperature lubricants and sewage pipes because of its excellent high temperature stability and lubrication properties.
?3. Optical glass: for the preparation of hydrogen fluoride, and then the synthesis of high quality optical glass.
?4. Metallurgical industry: used as a flux in the smelting of cast iron, ferroalloys and non-ferrous metals to help remove impurities from the metals.
?5. Glass and ceramic industry: cryolite can be used in the manufacture of opalescent glass and enamel shading agent, providing good shading effect and opalescent effect. ?
?6. Agriculture: cryolite is also used as an insecticide for crops, which is effective in controlling pests 

7. Production of abrasives: as active filler in resin-bonded abrasives for metal treatment.

8. Metal surface treatment: as component in pickling pastes for stainless steel Glas-opacifier: as turbidity agents
