Aritificial cryolite powder, Synthetic Cryolite(Na3AlF6), Sodium Aluminum Fluorid

Aritificial cryolite powder Synthetic Cryolite(Na3AlF6)/ Sodium Aluminum Fluorid F: 53%min white powder

Synthetic Cryolite(Na3AlF6)/ Sodium Aluminum Fluorid

Chemical name: Sodium Fluoroaluminate  Molecular formula: Na3AlF6 Molecular weight: 209.94

CAS: 13775-53-6

Physical Properties:

The size distribution can be crystalline powder (200mesh, 325mesh) , sandy(80mesh), granular(0-10mm) ,Slightly soluble in water, density 2.95-3.0, melting point 1000°C, 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.

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.
