We also attainted mosi2 / sic composite by using melting mosi2 infiltrated sic body which shaped by sic powder . the result show that the diameters of sic particle and shaping methods have effect on the composite ' s microstructure and properties 另外,尝试了用mosi _ 2在2050下浸渗直接由sic粉体成型的坯体制备mosi _ 2 / sic复合材料。采用sic颗粒的级配有利于提高坯体密度,但是降低烧结体的致密度。
