| 摘 要： | 研究了通过磷酸化工艺制备多孔球形羟基磷灰石的可行性. 利用(NH4)2HPO4, Na2HPO4溶液或其混合溶液，在微波加热条件下对粒度约15 mm的球形碳酸钙进行磷酸化处理，通过ESEM, XRD和EDS等手段进行表征. 结果表明，在微波加热条件下，球形碳酸钙通过与HPO42-发生阴离子交换反应，可在15 min的较短时间内转化成羟基磷灰石主相. 不同组成的HPO42-处理液对微波加热转化反应的历程有显著影响，进而影响颗粒形貌、结构和物相组成. 在不同条件下可制备出从绒毛状到细小颗粒堆积体等不同形状的多孔球形羟基磷灰石.

| Abstract: | The porous spherical hydroxyapatite particles were prepared by phosphoration of calcium carbonate with solutions containing (NH4)2HPO4, Na2HPO4 and their mixtures under microwave heating, and the products were characterized by ESEM, XRD and EDS. The experimental results showed that calcium carbonate particles were converted rapidly into hydroxyapatite after microwave treatment for 15 min. The composition of phosphoration solution has strong effect on the morphology and crystallization of the product. Hydroxyapatite with different spherical structures of fuzzy or fine particles aggregated morphologies were obtained under different conditions. |
