Abstract

Results of studies of the effect of the preparation of charges of modified powders and sintering additives on the uniformity of their distribution in the matrix and the sintering, structure, phase composition, and properties of silicon carbide materials obtained by hot pressing are presented. The possibility of controlling the processes of formation of internal and surface defects in SiC grains, the structural defects of SiC crystals, and the synthesis of nuclei of the hardening phases by modifying the powders with hetero-organic substances makes it possible to control the composition — structure — properties relation and obtain strong and crack-resistant silicon carbide materials. The presence of Β-SiC nuclei and modified powders makes it possible to fabricate a high-strength and crack-resistant material (at least 6.5 MPa · m1/2).
