The effect exerted on the hardness and open pores ratio of preforms by coarse and fine SiC particles and the addition of Al2O3 particles was analyzed. The results showed there are a lot of elements which effect the quality of preforms. As for pure SiC preforms , the coarser of the SiC particles, the higher of the hardness of preforms and the higher of the open pores ratio. The addition of Al2O3 particles improves the hardness of SiC preforms, the coarser of the SiC particles, the lower of the hardness of preforms and the higher of the open pores ratio. 目录 4.2.3烧结的影响…………………………………………………………………………… 11
