Microwave Synthesis and Characterization of Nano-sized Calcium Deficient Hydroxyapatite with Different Ca/P Ratio

Abstract

通过微波辐射硝酸钙和磷酸的共沉淀物可以快速合成不同CA/P比的缺钙羟基磷灰石,利用fT-Ir、fT-rAMAn和Xrd对产物进行了表征,EdS测定CA/P比,TEM观察其形貌。结果表明,通过控制反应条件能得到不同CA/P比的纳米缺钙羟基磷灰石。Rapid synthesis of calcium deficient hydroxyapatite with different Ca/P ratio was done by precipitation using calcium nitrate and phosphoric acid and subsequently subjecting to microwave irradiation.The synthesized CDHA was characterized by FT-IR, FT-Raman, and XRD.Ca/P ratio was determined by EDS.Transmission electron microscopy analysis showed needle like or stick like morphology of CDHA.In all, nanosized CDHA with different Ca/P ratio can be synthesized by controlling reaction condtion.福建省科技重大专项资助(2005HZ01-3
