摘要
概述了化学计量比HA及缺钙型HA在高温下的热分解机制,综述了国内外对HA热稳定性研究的成果,总结了通过提高钙磷比、向晶格中引入F-或K+、改变测试气氛等提高HA热稳定性的方法及其机理,展望了制备高温稳定的HA粉末和晶须的研究方向和可能的途径。
The mechanisms of decomposition about stoichiometric HA and calcium-deficient HA are described firstly, then the research results on thermal stability of HA are reviewed. And some methods to improve the thermal stability of HA, such as increasing Ca/P, introducing other ions into crystal lattice of HA, changing atmosphere of testing and so on, are summarized. The possible routes of preparing HA with high thermal stability are put forward.
