Abstract

The objective of the present study has consisted in obtaining and studying the properties of the composite material based on silicon carbide and corundum. The synthesis process of the composite material is effected by means of adding aluminum to the traditional charge used in the technology of silicon carbide obtaining by the reaction of SiO2+3C=SiC+2CO (eq 1). The adding of aluminum into the said charge stipulates its flow in accordance with the reaction of SiO2+C+4/3 Al=SiC+2/3 Al2O3 ↔ SiC-Al2O3 (eq 2). The reaction (2) proceeds to form the composite material of the two-phase system SiC-Al2O3 that represents the aggregate of many grains of silicon carbide SiC allocated in the corundum matrix Al2O3.
