Al2O3-TiN micro-composite powder was prepared by reduction and nitridation of mixed Al2O3-TiO2 powder. By adding Ti-isopropoxide as TiO2 source, TiO2-coated Al2O3 grain was obtained. A suitable condition for the reduction and nitridation was determined at 950-1450°C in a flowing mixed N2-H2 gas, with suppressed grain growth and sufficient nitridation. A partial coating was observed in Al2O3-TiN composite powder as well as in the Hot-pressed sintered body, which enhances the electric conductivity. Therefore, this method is promising for preparing materials for electric discharge machining.
