Sodium hexafluoroaluminate (Na3AlF6) is a chemical compound. It is a stable compound although will decompose when reacted with aluminium oxide (Al2O3), or sodium oxide (Na2O). Cryolite is the naturally occurring mineral form of the compound.

Conditions/substances to avoid are thermal decomposition and strong acids.

Applications

This compound is used in the production of insecticides, in the glass and enamel industries, as well as being a solvent for bauxite in the electrolytic manufacture of aluminium.

afety Notes

Acute effects: If ingested, this compound may cause vomiting, cramps, nausea and diarrhea. Larger doses may affect the respiratory system, the bladder, the kidneys and the heart. Upon contact with the skin, this chemical may cause irritation and, in more severe cases, skin rashes. Contact with the eyes or inhaling the substance will also cause some irritation.
