Abstract
A process for producing titanium metal in finely-divided particulate form, by forming a liquid mixture of titanium and zinc, fracturing and solidifying the liquid mixture and evaporating zinc from the resulting finely-divided particles to produce finely divided particulate titanium. Titanium alloys may be produced by adding an alloying metal or metals to the liquid titanium-zinc mixture prior to fracturing, solidification and zinc evaporation. The liquid mixture of titanium and zinc may be produced by reaction of a reducing metal in a liquid mixture of zinc and reducing metal with titanium tetrachloride to produce reducing metal chloride and a liquid mixture of titanium and zinc. The reducing metal chloride is separated from the mixture of titanium and zinc. The alloying metal may be added to the liquid mixture of titanium and zinc by reacting alloying metal chlorides with the reducing metals in the liquid mixture of zinc and reducing metal. Sponge titanium or titanium alloys may be produced by omitting the fracturing and solidification step.
