Abstract
A process for producing titanium metal sponge within a closed cell system involving the electrical decomposition of molten magnesium chloride into magnesium metal and chlorine gas within a closed cell to form said magnesium metal as a molten layer upon said magnesium chloride; terminating said electrolytic decomposition, and subsequently; directly contacting titanium tetrachloride with said layer of magnesium metal for effecting a reduction reaction therebetween within the same closed cell to form titanium metal sponge and magnesium chloride and removing said titanium metal sponge from said closed cell. The chlorine gas by-product can be used to form titanium tetrachloride from a titanium ore/coke mixture.
