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。
The crystal structure of apatite was described in detail, and the chemical bonding forces between the elements of the coordination polyhedrons in the apatite structure were calculated by various methods. The surface properties of the apatite were analyzed. A typical phosphate rock sample in typical phosphate rock area of Guizhou is composed of microcrystalline apatite. The phase composition, crystallinity, unit cell parameters and phosphorus content of the phosphate rock sample were analyzed by X-ray diffraction Graystone grain size. Under the scanning electron microscope, the two kinds of phosphate rock phosphate were mostly aggregates, and the phosphate minerals in the two kinds of phosphate rock mainly consisted of fluorapatite.
