| 摘 要： | 详细叙述了磷灰石的晶体结构，并采用多种方法对磷灰石结构中配位多面体各元素间的化学键力进行计算，分析了磷灰石的表面特性。针对贵州典型磷矿区具有代表性的胶磷矿试样，其主要由微晶磷灰石组成，采用x射线衍射分析了胶磷矿试样的物相组成、结晶度、晶胞参数以及磷灰石晶粒大小。在扫描电子显微镜下，2种胶磷矿多呈集合体形态，两种胶磷矿中磷酸盐矿物主要为氟磷灰石。

| Abstract: | Crystal chemistry and chemical bonding calculation of apatite structure were summarized in this paper.The collophanite consists chiefly of microcrystalline apatite.The X-Ray diffraction was applied to analysis the phase,crystallinity,unit cell parameters and crystal size of collophanite.Results of scanning electron micrography with energy dispersive spectrometry show that the main mineral is fluorapatite. |
