摘要 在柠檬酸和硫酸镁溶液中同时直接引入二水石膏与羟基磷灰石(hydroxyapatite,HA)共水热合成,获得了一种具有HA表面修饰的α-半水石膏的复合颗粒,并分析了该复合颗粒的成分、形貌、微观结构。结果表明:水热合成的颗粒是以α-半水石膏为主体,有HA在其表面修饰;随着HA的添加量的增加,HA表面修饰层的覆盖范围明显增加。 The a-calcium sulfate hemihydrate particles modified with hydroxyapatite (HA) were prepared with calcium sulfate dihydrate and HA in a mixed electrolyte solution of citric acid and magnesium sulfate by a co-hydrothermal method. The crystalline phase, morphology and microstructure of the HA modified a-calcium sulfate hemihydrate particles were characterized by X-ray diffraction, Raman spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, differential scanning calorimetry and thermogravimetry, respectively. The results indicate that the composite particles after surface modification can be prepared by the co-hydrothermal synthesis method. The more HA could be deposited on the surface of a-calcium sulfate hemihydrate particles when the content of HA in the electrolyte was increased.
