不同钙源的羟基磷灰石的合成及表征

摘要

Synthesis methods of hydroxyapatite with different calcium sources under hydrothermal conditions were compared.From SEM,XRD and FT-IR results,it is concluded that the eggshell could be used as an effective source of Ca2+,and its porous structures could also be selected as a hard template in the formation of flower-like hydroxyapatite.Sodium dihydrogen phosphate was used as the sources of PO43-to corrode the CaCO3 to hydroxyapatite.The result indicated that the sodium phosphocreatine would have a wide application prospect in the synthesis of high purity hydroxyapatite by hydrothermal decomposition.%通过比较法研究了不同钙源在水热条件下合成羟基磷灰石的方法.SEM,XRD和FT-IR的测试结果表明,蛋壳不仅可以成为有效钙源,而且多孔结构还可充当硬模板,在磷酸二氢钠缓慢腐蚀CaCO3的同时提供PO43-诱导生成花状羟基磷灰石.研究表明,磷酸肌酸钠水热缓慢分解释放磷酸根在合成高纯度羟基磷灰石方面有着广阔的应用前景.
