'''Sodium hexafluoroaluminate''' ([[Sodium|Na<sub>3</sub>]][[Aluminium|Al]][[Fluorine|F<sub>6</sub>]]) is a [[chemical compound]]. It is a stable compound although will decompose when reacted with [[aluminium oxide]] (Al<sub>2</sub>O<sub>3</sub>), or [[sodium oxide]] (Na<sub>2</sub>O).
Conditions/substances to avoid are [[thermal decomposition]] and strong [[acid]]s.
==Applications==
This compound is used in the production of [[insecticide]]s, in the [[glass]] and [[Vitreous enamel| enamel]] industries, as well as being a [[solvent]] for [[bauxite]] in the [[electrolysis|electrolytic]] manufacture of [[aluminium]].
==Safety 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 rash]]es. Contact with the eyes or inhaling the substance will also cause some irritation.
