Goal: To obtain SIALON containing composites by reactive sintering method in SiC-B4C-Si-Al-Al2O3system. Using this method of synthesis, it became possible to obtain composites with different percentages of SIALON. Our task was also to study the phase composition in the SiC-B4C-Si-Al-Al2O3 system. Method:The obtained mass was grounded in an attritor and the consolidated composite was obtained by hot pressing at 1800°C, 40 minutes, delaying at final temperature for 8 min. under 30 MPa pressure. To study the phase composition of the composites, we conducted an X-ray structural analysis on the DRON-3 device, and to study the microstructure, we conducted research on an optical microscope and a raster electron microscope
