以鸟蛤壳废料为起始原料，通过水热法成功合成了羟基磷灰石颗粒Ca-10(PO4)(6)(OH)(2)，(HAp)。鸟蛤壳经过煅烧、水合（熟化）并进行碳酸化，形成沉淀碳酸钙 (PCC)。 PCC 中添加 (NH4)(2)HPO4，通过在碱性条件（pH 10-11）下改变温度和反应时间形成 HAp。 X射线衍射（XRD）图表明，通过简单的水热程序（140℃，16小时）可以获得具有六方晶体结构的HAp的优异产物。傅里叶变换红外光谱 (FTIR) 光谱分析显示存在 OH、HPO42- 和 PO43- 吸收带，表明形成了 HAp。干燥后的HAp颗粒粉末极其纯净，比表面积为17.8 m(2)/g。
Hydroxyapatite particles, Ca-10(PO4)(6)(OH)(2), (HAp), have been successfully synthesized by hydrothermal method using cockle shells (Anadaragranosa) waste as the starting material. The cockle shells were calcined, hydrated (slaking) and undergone carbonation to form precipitated calcium carbonate (PCC). The PCC was added with (NH4)(2)HPO4 to form HAp by varying the temperatures and reaction times under basic condition (pH 10-11). The X-ray Diffraction (XRD) patterns revealed that the excellent product of HAp with hexagonal crystal structure can obtained via facile hydrothermal procedure (140 degrees C for 16 h). Fourier transform infrared spectroscopy (FTIR) spectra analyses showed the presence of OH, HPO42-, and PO43- absorption bands, indicating the formation of HAp. The dried HAp particles powder was extremely pure with a specific surface area of 17.8 m(2)/g.
