Materials based on silicon carbide (SiC) and the SiC–20B4C–1C–0.5B system were produced using spark plasma sintering. The properties of powder mixtures and finished products were studied using thermal analysis, electron microscopy, X-ray diffraction analysis, and flexural testing. Thermal analysis showed that SiC powders with B and C additives had an accelerated mass loss, indicating their ability to sinter more effectively and form a grain boundary phase consisting of boron-carbon compounds. The addition of boron carbide led to the formation of an additional hardening phase in SiC. The main phase in the material was 6H-SiC polytype with a hexagonal alpha-SiC structure. Mechanical testing of the SiC-20B4C-1C-0.5B composite material revealed that its bending strength at RT reached 332 MPa. The study was not completed.
