CRYOLITHE SODIQUE

SODIUM CRYOLITE

Ref : CRYOLIT

Cryolite, or natural sodium aluminium fluoride, is an interesting element because it provides a safe source of sodium in its natural, non-sintered form.

It is used whenever sodium and alumina are required together in the same glaze.

It provides the characteristic colour reaction to sodium or highly alkaline fluxes.


Cryolite: Sodium Hexafluoroaluminate or Sodium Fluo-Aluminate (Molecular Formula AlF6Na3, contains 32.9% Na, 12.8% Al, 54.3% F) may also contain traces of Fe and Ca.

Main deposits : Cryolite of the Ivitgut Complex (Greenland)

Mineral associated with large pegmatite deposits.
