Abstract

In this work, high-temperature reaction process with gaseous nitrogen led Si and Ti powders, Si and titanium suicide powders or titanium suicide powders to two phase ceramic composites consisting of SI3N4 (α-Si3N4 and β-Si3N4) and TiN. The results of X-ray diffraction analysis showed there are remarkable differences in the ratio of α-Si3N4/β-Si3N4 between the specimen used elemental powders and that used intermetalic powders. That is mainly caused by a difference in the starting temperature and reactivity of silicon nitridation. Thus, it is promising for synthesis of Si3N4-TiN composite powders to use intermetalic powders.
