Electro-deoxidation of solid chromium oxide in molten chloride salts (2005)
Presentation / Conference
Gordo, E., Chen, G. Z., & Fray, D. J. (2005, February). Electro-deoxidation of solid chromium oxide in molten chloride salts. Paper presented at TMS Annual Meeting 2005, San Francisco, California, U.S.A

Chromium is industrially produced by aluminothermic reduction of Cr 2O3 or electrodeposition from the aqueous NH 4Cr(SO4)2 solution. The former makes more a expensive product than an electrolytic method because the reductant, aluminium, is produced b...
