Characterization of synthetic calcium phosphates is reported and compared with previous studies. Barium hydroxyapatite was also synthesized. Shrinkage on sintering, water absorption, tensile strength, porosity and X-ray diffraction patterns were studied. Hydroxyapatite and beta-tricalcium phosphate show compositional and mechanical property variation dependent on sintering temperatures. The property change on introduction of barium removes the practical value. X-ray diffraction analysis is considered essential before clinical use due to sensitivity of composition to sintering conditions.
本文报道了合成磷酸钙的特性，并与之前的研究进行了比较。还合成了钡羟基磷灰石。研究了烧结收缩率、吸水率、拉伸强度、孔隙率和X射线衍射图谱。羟基磷灰石和β-磷酸三钙的成分和机械性能随烧结温度而变化。引入钡后性能的变化使其失去了实际应用价值。由于成分对烧结条件敏感，在临床使用前进行X射线衍射分析被认为是必不可少的。
