| 摘 要： | 本工作采用造孔剂（ＰＦＡ）干压工艺制备羟基磷灰石多孔陶瓷。通过两种造孔剂制得的多孔羟基磷灰石陶瓷性能的对比，发现两种造孔剂可制得多孔羟基磷灰石陶瓷。并借助ＳＥＭ、压汞仪等仪器和设备，对多孔体的性能进行了测试，讨论了造孔剂粒径、添加量及形状对多孔体性能的影响，结果表明：采用碳粉作造孔剂制得的多孔体具有较高的强度，而采用聚甲基丙烯酸甲酯（ＰＭＭＡ）作造孔剂制得的多孔体孔径的可控性高。

| Abstract: | Polymethyl methacrylate(PMMA)and carbon powder were used as the poreforming agents (PFAs) to prepare porous hydroxyapatite ceramics. The influences of the particle size and the additive amount of each PFA on the properties of the ceramics were discussed. The results showed that the porous bodies with carbon powder and with PMMA have higher strength and good controllability of pore size respectively. |
