摘要：

Silicon-carbide materials with 5 - 10 wt.% additions of oxides were prepared by liquid-phase sintering at 1860 - 2100 degrees 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.
