摘　　要：采用有机泡沫浸渍制备Al2O3基泡沫陶瓷,研究黏土加入量对陶瓷性能的影响。研究结果表明:随着黏土含量的增加,试样的热震稳定性先升后降,抗压强度先升后降、又略有上升。黏土质量分数为6%时,泡沫陶瓷性能最好,此时抗压强度为1.70 MPa,热震循环次数为12次。In this paper,Al2O3 ceramic foam filters were prepared by polyurethane sponge impregnation. The effect of clay on properties of ceramic foam was studied. The results show that with the increasing of clay content,thermal shock properties are increased first and then decreased. The compression strength is increased first,then decreased and increased again. When clay content is 6%,the properties of ceramic foam are the best with the compression strength and thermal shock times being 1. 70 MPa and 12 respectively.
