Hydroxyapatite powder was mechanochemically synthesized from calcium pyrophosphate (Ca2P2O7) and calcium carbonate (CaCO3) using a solid-state reaction. The two powders were mixed in distilled water, milled for 8 hours, dried and calcined at 1100 degrees C for 1 hour. The phase(s) formed was analyzed by x-ray diffraction (XRD). It was found that hydroxyapatite was not the only one formed. This result will be used as the starting point to produce a single-phase hydroxyapatite in terms of excess hydroxyl group in a mechanochemical reaction.
采用固态反应法，以焦磷酸钙（Ca2P2O7）和碳酸钙（CaCO3）为原料，通过机械化学合成法制备了羟基磷灰石粉末。将这两种粉末在蒸馏水中混合，研磨8小时，干燥后在1100℃下煅烧1小时。通过X射线衍射（XRD）分析所形成的物相。结果发现，羟基磷灰石并非唯一形成的产物。该结果将作为在机械化学反应中通过过量羟基来制备单相羟基磷灰石的起点。
