水热法合成羟基磷灰石

Hydrothermal Synthesis of Hydroxy Apatite

本文进行了水热法合成羟基磷灰石的实验室研究,研究了配料比,反应温度和时间的影响,确定了适宜工艺条件。化学分析和红外光谱测定结果表明合成产品以羟基磷灰石为主;经洗涤的产品可达到较高的纯度。

Hydroxy apatite is syntnesised hydrot hermal ly in the labooratory. The ef-fects of the feed ratio,the tempera ture,and the reaction time are studied to determine the optimal operating conditions.The results of chemical and infra-red spec t romel r ic analysis show that the majority of the product synthesised is hydroxy apatite,and the product washed with a solution of NH4C1 can achieve very h igh purity.
