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．

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.
