Two processes are proposed to produce Ti powder directly from TiCl4 gas using molten magnesium as reductant. TiCl4 gas injection into a liquid Mg layer through the molten chloride salts could produce the Ti powder of 1 to 10 mm in diameter. Neither the operation temperature nor the salt composition affected the powder morphology. When TiCl4 was dissolved once in the molten salt as Ti2+, and when Mg successively reduced this Ti2+, the Ti morphology varied from the needle-like to the round shape by raising the reduction temperature.
