在选冶过程的物质组成研究中,广泛遇到细小晶粒的共生矿物、冶炼产品或其它类似混合物的相组成研究,也常常遇到稀少、稀散元素的相分析。对于这些类型的问题,往往由于难以获得足够纯度或足够数量的单矿物供X射线衍射相分析用,从而使问题难以解决。因此,选用单个纯的微进行X射线衍射分析就十分迫切。所谓“单微粒”,是指直径为100微米左右或100微米以下(即重量为微克或微克以下)的单个颗粒。长期以来,人们一直在 In the study of material composition in the process of metallurgy and metallurgy, the phase composition of the coexistent minerals, smelting products or other similar mixtures with fine grains is widely encountered. Phase analysis of sparse and scattered elements is also often encountered. For these types of problems, it is often difficult to solve problems because it is difficult to obtain a single mineral of sufficient purity or a sufficient amount for X-ray diffraction phase analysis. Therefore, the choice of a single pure micro-X-ray diffraction analysis is very urgent. By “single particle” is meant a single particle having a diameter of about 100 microns or less (ie, a weight of micrograms or less). People have been around for a long time
