Abstract : The development of titanium powder metallurgy has imposed new demands on the quality of the initial powders whose properties, especially purity, form, and particle size, vary within a wide range depending on the method of their production. At present, titanium production is developing in the following basic directions: reduction of titanium from its oxides and halide compounds; electrolysis and electrolytic refining of wastes; vacuum distillation of titanium vapors for obtaining high-purity powders; various ways of grinding titanium sponge and titanium-containing materials, including titanium hydrides, with their subsequent degassing; or by a combination of these processes. The reduction of titanium chlorides by magnesium, calcium, or lithium involves griding the reaction products and leaching them with nonaqueous solutions (alcohol, acetone, etc.), which complicates the technological system of producing the powders and has a negative effect on their properties.
