采用简单的水热法，在低温（110-200 °C）NaOH溶液中反应14 h，直接合成了一系列钒酸盐取代羟基磷灰石。通过X射线粉末衍射、ICP化学分析、氮气物理吸附、TEM和FTIR测量对磷灰石样品进行了表征。钒酸盐/磷酸盐羟基磷灰石固溶体，即，Ca 10（VO 4）x（PO 4）6−x（OH）2（xεI=0、1、2、3、4、5和6），具有单相磷灰石结构。晶格常数随V含量（x）的增加而线性增加，且符合Vegard定律。所有的Ca 10（VO 4）x（PO 4）6−x（OH）2（x=I）样品在3560 cm−1附近显示出OH振动带。所述白色磷灰石样品为柱状晶体，其长度约为40-100 nm，宽度约为25-40 nm。
A series of vanadate substituted hydroxyapatite was directly prepared by a simple hydrothermal method at low temperature (110–200 °C) in NaOH solutions for 14 h. The apatite samples were characterized by powder X-ray diffraction, ICP chemical analysis, nitrogen physisorption, TEM, and FTIR measurements. The vanadate/phosphate hydroxyapatite solid solution, i.e., Ca10(VO4)x(PO4)6−x(OH)2(xεI=0, 1, 2, 3, 4, 5, and 6), had a single phase of apatite structure. The lattice parameters increased linearly with increasing V content (x) with obeying the Vegard's law. All Ca10(VO4)x(PO4)6−x(OH)2(x=I) samples showed the OH vibration band around 3560 cm−1. The white apatite samples were column crystals with length of about 40–100 nm and width of about 25–40 nm.
