【 摘 要 】

Dense ceramic materials based on SiC with an oxide activating additive YAG by hot pressing at a temperature of 1850 ° C were obtained. The oxides, melting, fill the space between the SiC particles, contributing to the compaction and mass transfer of the material in the process of hot pressing. It is shown that for a high compaction of the SiC-YAG material, a small amount of oxides is necessary-9 wt. %
