  • Patent number: 5032176
    Abstract: A method for manufacturing a titanium powder, which comprises the steps of: causing a molten reducing agent comprising molten magnesium at a temperature of 650.degree. to 900.degree. C. or molten sodium at a temperature of 100.degree. to 900.degree. C. to fall into a reaction vessel; ejecting a titanium tetrachloride gas at a temperature of 650.degree. to 900.degree. C. toward the falling flow of the molten reducing agent in the reaction vessel to atomize the molten reducing agent, and producing titanium particles containing molten reaction product which comprises molten magnesium chloride or molten sodium chloride, through a reducing reaction between the atomized molten reducing agent and the titanium tetrachloride gas; and removing the reaction product from the titanium particles containing the reaction product to manufacture a titanium powder.
