采用水相沉淀法直接制备了一系列砷酸盐取代的氯磷灰石。元素分析、XRD、FT-IR 光谱和 SEM 的表征研究证实了砷酸盐/磷酸盐氯磷灰石固溶体的形成。 XRD分析表明磷灰石型结构的典型固溶体相。在FT-IR光谱中，随着砷酸盐比例的增加，磷酸盐峰的面积逐渐被抑制，砷酸盐峰的面积逐渐增大。 As/(As+P)摩尔比为0.49~1.0的固体为针状晶体； As/(As+P)摩尔比<0.19的为大板状。
A series of arsenate substituted chlorapatite was directly prepared through aqueous precipitation method. Characterization studies from elemental analysis, XRD, FT-IR spectra and SEM confirmed the forming of the arsenate/phosphate chlorapatite solid solutions. The XRD analysis indicated the typical solid solution phase of the apatite-type structure. In FT-IR spectra, the area of the phosphate peak was gradually suppressed and the arsenate peak increased as the proportion of the arsenate increased. The solids with As/(As+P) molar ratio of 0.49~1.0 were needle-like crystals; those with As/(As+P) molar ratio <0.19 were large tabular.
