Abstract
Disclosed herein is a method for reducing a metal oxide in a metal oxide containing precursor. The method comprises providing a reaction mixture comprising the metal oxide containing precursor and an aluminium reductant; heating the reaction mixture in the presence of solid or gaseous aluminium chloride to a temperature at which reactions that result in the metal oxide being reduced are initiated; controlling reaction conditions whereby the reaction mixture is prevented from reaching a temperature at which thermal runaway can occur; and isolating reaction products that include reduced metal oxide.
