Experimental Study on the Synthesis of Nano-Hydroxyapatite underHydrothermal Condition
水热合成羟基磷灰石纳米粉体的研究

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.
