Аннотация

Silicon-carbide materials with 5 – 10 wt.% additions of oxides were prepared by liquid-phase sintering at 1860 – 2100 °C. The highest physicomechanical properties were achieved in SiC material containing 20 wt.% of a three-component eutectic composition in the MgO–Y2O3–Al2O3 system. The mechanical characteristics of liquid phase-sintered materials containing 15 wt.% of the three-component oxides additive exceed those of both the reactive-sintered and the solid-phase sintered materials and approach those of hot-pressed materials. Ill. 5. Ref. 30. Tab. 2.
