Abstract
A method of increasing the apparent density of agglomerated ligmental titanium or titanium alloy powder produced by the subsurface reduction of titanium tetrachloride vapor or a mixture of titanium tetrachloride and other halide vapors in a flowing stream of alkali or alkaline earth metal or mixtures thereof having a first apparent density after distillation is disclosed. The agglomerated ligmental titanium or titanium alloy powder is introduced into an attriting system wherein the agglomerated ligmental titanium or titanium alloy powder is attrited until the powder becomes more spherical than ligmental and the first apparent density is increased by a factor of from about 3 to about 8. Inert atmosphere may be used to prevent unwanted oxygen contamination.
