采用ＣａＣＯ３和ＣａＨＰＯ４·２Ｈ２Ｏ的混合物为前驱物,通过水热合成得到晶粒完整、分散性好、端面粒度在１００ｎｍ以下的ＨＡ粉体,并借助ＸＲＤ和ＳＥＭ分析讨论了前驱物配比、水热温度、反应时间与物相组成、粒度变化和晶体形貌的关系．
Hydroxyapatite(HA) was synthesized by using CaCO3 and CaHPO4·2H2O as raw materials under hydrothermal condition. The relation between ratio of raw materials, hydrothermal temperature, reaction time and the resultant phases, changes of granularity, crystal appearance were studied by using SEM and XRD. This HA synthesized has a good crystal appearance, good dispersity, its end plane granularity is less than 100 nm.
