Materials with a nanosized oxide additive of yttrium aluminum garnet were obtained by the method of liquid-phase sintering. Sintering of materials based on SiC and Si 3 N 4 was carried out at temperatures 100 ° C below the sintering of materials with the addition of micron-sized oxide powders. High mechanical properties were obtained: & # 963; bend = 540 MPa, K1C = 5.5 MPa m1 / 2, НV = 20.1 GPa for materials based on SiC and & # 963; out = 650 MPa, K1C = 6.4 MPa m1 / 2, НV = 17.2 GPa for materials based on Si 3 N 4
