粉晶Ｘ射线衍射分析研究结果表明，不仅土状坡缕石与纤维状坡缕石两者间存在着结晶度的差异。而且分析样品中可能存在着两个坡缕石矿物相。它们分别具有原始格子和底心格子两种结构类型。肯定的指出：２０°＜２θ＜３０°和３４°＜２θ＜４５°衍射区的衍射峰差异唯有可能是坡缕石晶体结构格子类型的变化所致而非由斜方晶系变为单斜晶系时（１２１）及（１６１）衍射峰分裂所致（Ｃｈｒｉｓｔｅｔａｌ．，１９６９）。研究坡缕石属于单斜晶系，主要表现为Ｃ２／ｍ空间群并可能有Ｐｂｍｍ（Ｐｒｅｓｉｎｇｅｒ．１９６３）．晶胞参数ａ＿０值与矿物的晶体化学成分有密切的负相关关系。β值可从近于９０°变化至１００°。
The results of X-ray powder diffraction analysis show that not only the difference of crystallinity exists between the soil-like palygorskite and the fibrous palygorskite. Moreover, there may be two palygorskite phases in the analysis sample. They have the original lattice and the bottom lattice two structural types. It is pointed out that the difference of the diffraction peaks in the diffraction region of 20 ° <2θ <30 ° and 34 ° <2θ <45 ° is only possible due to the change of lattice type of the palygorskite structure rather than the change from the orthorhombic system to the single (121) and (161) diffraction peaks due to cleavage (Christetal., 1969). Study Palygorskite belongs to the monoclinic system, mainly in the C2 / m space group and probably Pbmm (Presinger.1963). Cell parameters a_0 value and the mineral crystal chemical composition has a close negative correlation. The value of β can vary from nearly 90 ° to 100 °.
