Abstract


A process for production of titanium powder directly from TiCl4 by Mg-reduction in molten salt is proposed that the reactants, titanium chloride and magnesium, are diluted in molten salt for the purpose of homogeneous nucleation of titanium. The relationship between the solubility of titanium chloride in the molten salt and the morphology of produced powder was investigated experimentally. The size of powder increased as the solubility of titanium chloride in molten salt increased. The mechanisms of titanium growth in the Kroll process and in the proposed process are discussed.
