本研究采用固相烧结法制得了以ＺｎＦｅ２Ｏ４，ＬｉＦｅ５Ｏ８为主晶相的磁性生物陶瓷。米用磁天平、法拉弟磁秤、ＶＳＭ，ＸＲＤ，ＳＥＭ测试了材料的磁性能、组成及微观结构，并对材料进行了生物学及动物实验。结果表明：此材料具有良好的磁性能、化学稳定性及生物相容性，且无毒无害，是一种应用前景广阔的生物材料。此外，作者还探讨了材料的磁性机理。

The Study of the Magnetic Mechanism of the Magnetic Bio-ceramic Xu Xiaohong;Sun Shuzhen;Wu Jianfeng;Wu Hua;Zhu Tongbo(Lect., Dept. of Material Enginering, WUT. Wuhan 430070, China.)The authors have made a new magnetic bio-ceramic in which main crystalline phases are ZnFe2O4 and LiFe5O8 by solid-state sintetring. Its magnetic property,mineral compositions and microstructures have been studied by the Magnetic Balance,theFaraday Magnetic Balance,VSM,XRD and SEM. The biology and animal experiments havebeen carried out. The conclusions show that the material has fine magnetic property,andgood chemical stability and biocompatibility,and no toxicity. The material has a broad ofapplication prospects. In addition,the authors have approached the magnetic mechanism ofthe material.: magnetic; bio-ceramic; magnetic mechanism
