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, and used as a feedstock to produce aluminium in the
Deville process. Molten sodium tetrachloroaluminate is used as an electrolyte in
sodium-nickel chloride batteries. ==See also==
