摘要: 研究了磷酸盐类晶体中的络阴离子[PO4]-和[CaP6O24]16-在晶体中的结晶方位,与[ClCa6]11+八面体相互联结的稳定性决定了各个面族的生长速率.根据磷灰石各族晶面显露的习性,提出了采用人工生长的磷灰石做人工关节时,应该注意磷灰石的取向问题.平行于C轴方向生长的磷灰石有利于与人体骨骼的快速愈合.

关键词: 晶体结构, 负离子配位多面体, 结晶方位, 结晶习性

Abstract: The growth rate of each face was determined by the crystallographic orientations of anionic coordinations such as [PO4]3- and [CaP6O24]16-
in phosphate crystals and the stability of their combining with octahedral [ClCa6]11+. According to the crystal habit of appearance for each face in
phosphorite, the crystallographic orientation should be paid a great attention to the growth of phosphorite for its application on artificial joints. The
phosphorite grown in direction parallel with the c-axis will promote the recovery of bones in the human body.

Key words: crystal structure, anionic coordination polygedron, crystallographic orientation, crystal habit
