X-射线粉末照相定性分析法在分析化学中独具一格,因为它能确切指出试样中含有那些化合物,能够分辨同一化合物的不同晶态,这是古典分析方法和一些仪器分析方法所不能或不容易办到的。虽然它也有些缺点,但瑕不掩瑜,它对于复杂化合物的鉴别是有很大用处的。因之,它对于矿石的分析,陶瓷工业的改进,较复杂反应机构的研究,相图的构成,都起了不小的作用。祖国经济建设飞跃发展,科学研究工作必然应
X-ray powder photography qualitative analysis is unique in analytical chemistry because it specifies exactly which compounds are contained in a sample and is able to tell the different crystalline states of the same compound, which classical analysis methods and some instrumental analysis methods can not Or not easy to do. Although it has some shortcomings, it does not obscure it. It is very useful for the identification of complex compounds. Therefore, it plays an important role in the analysis of ore, the improvement of ceramics industry, the research of complex reaction mechanism and the composition of phase diagrams. The rapid development of the motherland’s economic construction, scientific research must be
