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.
