有一种深灰色呈玻璃微珠状材料,粒度为25～70μm。为分析其物相组成,用X射线衍射分析发现,衍射谱中无明显可见的衍射峰。众所周知,X射线衍射分析法,是分析晶体物质物相组成的一种非常有效、且迄今 There is a dark gray glass bead material, particle size 25 ~ 70μm. In order to analyze its phase composition, it was found by X-ray diffraction that there was no obvious diffraction peak in the diffraction spectrum. It is well-known that X-ray diffraction analysis is a very effective method of analyzing the phase composition of crystalline materials and so far
