生物压电陶瓷复合种植材料的制备与性能研究

A STUDY OF PREPARAATION AND PROPERTIES OF BIOLOGICAL PIEZOELECTRIC CERAMIC COMPOSITE IMPLANT MATERIALS

研究了一种新型的人工生物压电陶瓷复合种植材料─—ＨＡＢＴ生物压电陶瓷．对该种材料的压电性能、力学性能、热学性能、化学性能和生物学性能进行了初步考察和动物试验．结果表明，该材料既具有与人体组织相近的生物相容性和力学相容性，又具有相似于人体自然骨的压电性．该材料还能诱导骨组织的生长，符合生物安全性检测要求．

A new type of biological pietoelectric ceramic composite implant material(HABT)wasprepared.The piezoelectric, mechanic,thermal, chemical and biological characteristics of the materialwere invesigated and preliminary tests in animal's bodies were carried out.The experimental resultsshowed that the material has biological and mechanic compatibilities with human tissne and also haspiezoeleoericity which is similar to that of natural bone in human body. It could grow well in animalbodies and induce bone cell growth.The material Satisfies reqairements of biological safety test.
