本文描述了一种测定微晶粉末晶体体系的方法。在这个过程中，在静态和旋转磁场下，在单轴定向的微晶体悬浮液上进行x射线衍射测量。接下来是使用本研究中提出的流程图对获得的衍射图像进行分类。为了证明该方法的有效性，我们记录了由已知晶体体系制备的微晶悬浮液的衍射图像，这些体系包括三斜晶（d-阿拉伯糖醇）、单斜晶（纤维素二糖）、正交晶（l-丙氨酸）、四方晶（尿素）、三角晶（铋、方解石）、六方晶（锌）和立方晶（氯化钠）体系。根据所提出的程序，将晶体分类到各自的晶体系统中。测定的双轴晶系与所研究的微晶粉末的晶系一致。本文还讨论了晶体体系的晶格参数和空间群的确定。
A procedure for determining the crystal system of a microcrystalline powder is described. In this procedure,in situX-ray diffraction measurements are performed on a microcrystal suspension oriented uniaxially under static and rotating magnetic fields. This is followed by the classification of the obtained diffraction images using a flowchart proposed in this study. To demonstrate the validity of this procedure, diffraction images were recorded for microcrystalline suspensions prepared from known crystal systems including triclinic (d-arabitol), monoclinic (cellobiose), orthorhombic (l-alanine), tetragonal (urea), trigonal (bismuth, calcite), hexagonal (zinc), and cubic (sodium chloride) systems. The crystals were classified into their respective crystal systems following the proposed procedure. The determined crystal systems for biaxial crystals were consistent with the reported crystal systems of the microcrystalline powders investigated. Herein, determination of the lattice parameters and space groups for the crystal systems is also discussed.
