通过浸渍Fe的水溶液，在1150 ℃的空气中热处理，冷却至室温，成功地合成了Ca10(PO4)6FexOyHz式含Fe原子的磷灰石型固溶体。Ca10(PO4)6FexOyHz的晶胞体积随Fe含量的增加而增大。粉末X射线衍射数据和拉曼光谱的结构细化结果表明，掺入的铁离子在磷灰石晶格中占据了四重位置，远离通道中心。该方法可用于合成含过渡金属的新型磷灰石型功能材料。
Apatite-type solid solutions with the formula Ca10(PO4)6FexOyHzcontaining Fe atoms in the channel sites of Ca10(PO4)6(OH)2were successfully synthesized by impregnation with aqueous solution of Fe, followed by heat treatment at 1150 °C in air and cooling to room temperature. The unit cell volume of Ca10(PO4)6FexOyHzincreased with increasing Fe content. The results of structural refinement using powder X-ray diffraction data and Raman spectroscopy suggested that the incorporated Fe ions occupied four-fold sites, away from the center of the channel in the apatite lattice. This method may be useful for synthesizing novel apatite-type functional materials containing transition metals.
