Equimoler mixture of Ti and C powders with additions of 5-40 wt% of Al2O3 powder was molded by using an pressure-resistant metalic mold whose inner wall was covered with a carbon insulator. The mixture in the mold was ignited by a tungsten heater and, then, compressed under a pressure of 1 GPa (10000 atm). TiC-Al2O3(10wt%) body thus obtained had a microstructure in which TiC crystals of relatively small grain size were surrounded by non-crystalline phase con-taining Al2O3, and the maximum value of its Vickers hardness was 32.7 GPa.
