人工合成纳米羟基磷灰石的研究

STUDY OF SYNTHETIC NANO-SIZE HYDROXYAPATITE

以磷酸二氢钙 ( Ca( H2 PO4) 2 · H2 O)和氢氧化钙 ( Ca( OH) 2 )的沉淀反应为基础 ,重点探讨反应条件、形核剂、干燥温度、烧结温度对羟基磷灰石形貌及尺寸的影响 .结果表明 ,通过控制反应温度、搅拌速度、反应时间及加入一定量的形核剂 ,可以得到纳米级。

The influences of reaction conditions, nucleation additives, dried temperature and stirring velocity on the size and morphology of Hydroxyapatite were discussed on the basis of the precipitation reactions between Ca(H 2PO 4) ·2H 2O and Ca(OH) 2 .The results showed that the nano-size and good dispersed Hydroxyapatite can be obtained by controlling reaction conditions, sinter temperature, stirring velocity and adding a certain quantity of nucleation additives.
