Ti powder (Na reduced, -60 mesh, 0.09 wt% oxygen) was resistance-sintered in air. The dependence of mechanical properties and corrosion resistance' of compacts on the condition of resistance sintering, particle size and history of the powder was studied. The compacts having low oxygen content (0.13%) and excellent mechanical properties (98% theoretical density, tensile strength 40-50 kg/mm2, elongation 30%) were obtained. The oxygen content in products is affected by the history of the powder rather than by the conditions of resistance sintering. When fresh powder is used, with increasing of power input per unit time and particle size, the oxygen content in the products decreases, resulting in more ductile Ti metal. Corrosion resistance of the resistance-sintered Ti increases with the increase of their apparent density, and their corrosion level is almost the same as that of conventional P/M Ti.
