Abstract

In this study, four SiBCN ceramic composites (BN+SiC+C, B4C+Si3N4+C, B2O3+C+Si3N4, B2O3+C+Si+AlN) were prepared by mechanical alloying and spark plasma sintering, and their phase, microstructure, open porosity, flexural strength and hardness were characterized. XRD analysis showed that the SiC and BCN were the main phases, in addition to BCN amorphous phase. The B2O3+C+Si+AlN composite had the best properties among the four composites, i.e., the porosity as low as 3.67%, the flexural strength of 133.031 MPa, and the Vickers hardness of 4.53 GPa.
