Abstract
Spark plasma sintering and hot compaction methods were used to obtain experimental samples of a composite material of the SiC‒SiCw system with various modifying additives (AlN, B4C, HfB2, Y2O3, Al2O3, Si3N4). The effect of the modifying additives on the sintering process, physicomechanical, and thermal properties of the ceramic composite material was examined. The introduction of the modifying additives lowered the sintering temperature of silicon carbide produced by the hot compaction method by 200°C and that formed with spark plasma spark sintering by 300‒450°C as compared with the sintering temperature of silicon carbide without additives.
