摘　　要：以α-Al2O3粉末为骨料,采用塑性挤压成型技术和固态粒子烧结法制备Al2O3多孔陶瓷支撑体。研究了粘结剂和成孔剂的种类对支撑体性能的影响。研究结果表明:通过选用合适的粘结剂和成孔剂,可制得孔径分布窄、孔隙率高的支撑体。A porous ceramic support comprising alumina was prepared by extrusion and solid sintering. The influence of binder and pore - forming agent kind on the properties of alumina support are studied. It is found that the supports ,which have narrow pore size and high porosity, can be prepared by adjusting proper binder and pore - forming agent.

关 键 词：多孔陶瓷支撑体 成孔剂 粘结剂
