Production and uses

Sodium tetrachloroaluminate can be prepared from sodium chloride and aluminium trichloride.

In the 19th century, it was produced industrially by carbochlorination of alumina in the presence of sodium chloride,^[2] and used as a feedstock to produce aluminium in the Deville process.^{[citation needed]}

Molten sodium tetrachloroaluminate is used as an electrolyte in sodium-nickel chloride batteries.
