磷灰石可作为生物陶瓷材料用于牙和骨植入体。红外（4000至400 cm-1）和激光拉曼光谱获得了水热制备的羟基磷灰石与通式X10（PO 4）6（OH）2，其中X= Ca 2 + Sr 2+，Ba 2+，或Pb 2+的基本振动模式进行了识别和经验频带分配。对振动光谱的分析导致v2模式重新分配到更高波数、更低强度的带（例如Ca羟基磷灰石的470 cm− 1）。在振动光谱中注意到固态相互作用的影响，并通过因子群分析进行解释。一个忽略OH−离子位置的“有效”因子群C6 h最能描述羟基磷灰石的振动光谱。
Apatites can be used as bioceramic materials for tooth and bone implants. Infrared (4000 to 400 cm−1) and laser‐Raman spectra were obtained for hydrothermally prepared hydroxyapatites with the general formula X10(PO4)6(OH)2where X= Ca2+Sr2+, Ba2+, or Pb2+Fundamental vibrational modes were identified and empirical band assignments made. Analysis of the vibrational spectra led to the reassignment of thev2mode to a higher wave‐number, lower‐intensity band (e.g. ∼470 cm−1for Ca hydroxyapatite). Effects of solid‐state interaction were noted in the vibrational spectra and interpreted by factor‐group analysis. An “effective” factor group C6h, which neglects the locations of the OH−ions, best describes the vibrational spectra of the hydroxyapatites.
