摘　　要：以炭黑和自制的PS微球(聚苯乙烯微球)、PMMA微球(聚甲基丙稀酸甲酯微球)为造孔剂制备氧化铝多孔陶瓷,通过SEM和其他方法对其强度、密度、外观形貌进行比较。结果表明,用PS微球与PMMA微球为造孔剂的多孔陶瓷在强度、气孔率等这些方面对多孔陶瓷的影响相近,炭黑对多孔陶瓷的各方面影响最大,以炭黑为造孔剂的多孔陶瓷比以PS微球与PMMA微球为造孔剂的多孔陶瓷的强度大、但是气孔率的稳定性差且不易控制。Porous ceramics are widely used in metallurgy chemical industry, environmental protection, energy, biotechnology and other fields and achieved great economic and social benefits. Fabrication of porous AlO23 ceramic by different pore--making agent including carbon and PS microspheres （polystyrene microspheres）, PMMA microspheres （polymethyl methaerylate microspheres）, and to com- pare its performance. The results show that the porous ceramic is similar in strength, porosity using of PS and PMMA microspheres. The performance of porous ceramics addition carbon have larger changes , the intensity of porous ceramic using carbon larger than using PS and PMMA microspheres , but the stability of porosity is poor and difficult to control.
