SYNTHETIC CRYOLITE  

 

SYNONYM: SODIUM FLUOROALUMINATE  

Molecular formula: Na3AlF6 molecular weight: 209.94

1> Properties: it is crystalline white powder. Slightly soluble in water, density 2.95-3, melting point 1000oC, easily absorbing water and become damp, decomposed by strong acids like sulfuric acid and hydrochloride, then producing hydrofluoric acid and relevant aluminum salt and sodium salt.

2> Uses: mainly used in flux of electrolytic aluminum, pesticide, flux of ceramic colors, anti-rubbing filling agent of resin and rubber, electrolytic liquid for production of iron alloy rimmed steel and furnish of emery wheel

.

3> Packing: package can be 25/50/1000kg plastic woven bags with shrink film, or according to customers requirements.

4> Specifications: GB4291-1999
