Abstract:
The invention relates to powder metallurgy, in particular to a method for metallothermal reduction of feedstock elements made from feedstock being a solid solution of oxides of various elements in titanium oxide, using magnesium and/or calcium as reducing agents. Processes include hydrolysis of an aqueous solution of a titanium-containing salt to obtain primary particles of crystalline titanium oxide, calcination of a precipitate of titanium oxides/hydroxides, formation of feedstock elements from a milled powder of a solid solution of dopants in titanium oxide, reduction of feedstock elements in one step using calcium metal or reduction of feedstock elements in two steps, using magnesium metal or calcium metal in the first step, and calcium metal in the second step. The aim of the invention is to produce alloy powders of titanium metal with a particularly low oxygen content.
