摘要
采用真空烧结方法制备了SiC多孔陶瓷,研究了不同助烧结剂Al2O3-Y2O3、Si以及不同造孔剂丙烯酰胺聚合物、羧甲基纤维素(CMC)对SiC多孔陶瓷形貌和气孔率的影响。结果表明:与Si相比较,Al2O3-Y2O3更有利于促进SiC的烧结;以Al2O3-Y2O3为助烧结剂的试样比以Si为助烧结剂的试样具有较高的气孔率。
The porous SiC ceramics were prepared by vacuum sintering in this investigation, the effect of different sintering aids, Al2O3-Y2O3 and Si, and different pore formers, acrylamide copolymer and Carboxymethyl Cellulose （CMC） on the microstructures and porosity were studied. The results show that Al2O3-Y2O3 promotes the sintering of SiC more than Si. And porous SiC ceramics used Al2O3-Y2O3 as sintering aid possesses higher porosity compared with porous SiC ceramics with Si as sintering aid.
