Abstract:	The clean and fine Ti3Al and TiAl compound powders were produced directly from the oxide mixtures of TiO2 and Al2O3 by the calciothermic reduction using vapor calcium, liquid calcium or CaH2. This procedure consists of three steps: raw oxide blending, co-reduction and leaching. The history of the preparation of the oxide mixtures had no effect on the production of the powders of a desired composition. The use of CaH2 powder for the reduction gave better results than that of the other reductants on the oxygen contents in the reduced powders. The indication on stoichiometric control in this procedure is thermodynamically discussed.
