We had reported the vacuum mechanofusion prpoedure, applied to Mo-A1<SUB>2</SUB>O<SUB>3</SUB> composite in air or under low pressure. This paper describes the result of trying the Mo particle coating on A1<SUB>2</SUB>O<SUB>3</SUB> core particles with different Mo content. It was found that the more Mo particles remained not consumed for the composite particles, as the Mo particle composition in the mixed particles increased. Furthermore, the Mo-A1<SUB>2</SUB>O<SUB>3</SUB> composite powders obtained was sintered to compact by spark plasma technique. As the results, it was found that the compact prepared from the composite powder was more improved in density than the compact prepared from the mixed powders, and this effect was remarkable in early stage of sintering. It was dear that the density of sintered compacts became higher as Mo content of composite particles increased.
