Product Description

 

 

 

Cryolite powder CAS NO 15096-52-3 worked as solvent (or flux) for

 

electrolysis of aluminium oxides

 

 

 

 ►Description

1. Cryolite is one kind of odorless white solid or powder. The IUPAC Name of this chemical is

trisodium;hexafluoroaluminum(3-). This chemical belongs to the product categories which is

inorganics. It’s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride.

 

2. Cryolite is the inorganic compound with the formula Na3AIF6 . This white solid,

 

discovered by the Brazilian José Bonifácio de Andrada e Silva, occurs naturally as

 

the mineral cryolite and is used extensively in the industrial production of aluminium

 

metal. The compound consists of the sodium (Na+) salt of hexafluoroaluminate

 

(AlF63−).

 

3. Most cryolite is manufactured from aluminium oxides, hydrofluoric acid, and

 

sodium hydroxide or the equivalent reagent hexafluorosilicic acid:

 

6 NaOH + Al2O3 + 12 HF → 2 Na3AlF6 + 9 H2O

 

It was mined as cryolite at Ivigtût on the west coast of Greenland, until the deposit

 

was depleted in 1987.

 

4.Cryolite is poorly soluble in water, which mitigates problems. The LD50 = 600

 

mg/kg for the comparable compound aluminium trifluoride.

►Application

 

1. The main application of synthetic cryolite is as a solvent (or flux) for electrolysis

 

of aluminium oxides such as bauxite. The conversion of aluminium oxides into

 

metallic aluminium requires that the metal ions be dissolved so that they can accept

 

the electrons provided in the electrolysis cell. A mixture of cryolite and some

 

aluminium trifluoride is that solvent. Unlike typical solutions, this one requires

 

temperatures approaching 1000 °C to melt.
