粘土矿物广泛分布于地壳的表层,它的种类和含量的多少是陶瓷工业、工程建设等有关部门十分感兴趣的问题。因此,粘土矿物的定量分析研究有一定的实际意义。在目前粘土矿物的定量分析技术和方法中,有经典的内标法,外标法,以及国内外较多采用的强度比例因子法等。前者要求有纯粘土矿物标准样做基础,后者虽然不要求纯标样,但对不同粘土矿物之间(部分矿物)的X射线衍射强度作了一个经验比例关系假定。即在同样百分含量的情
Clay minerals are widely distributed in the crust of the surface, its type and content of the number of ceramic industry, engineering construction and other departments are very interested in the issue. Therefore, the quantitative analysis of clay minerals has some practical significance. In the current quantitative analysis of clay minerals and methods, there are classic internal standard method, external standard method, as well as the intensity ratio factor method used more at home and abroad. The former requires that pure clay mineral standards be used as a basis, while the latter, although not required for pure standards, assumes an empirical proportional relationship between the X-ray diffraction intensities of different clay minerals (partial minerals). That is the same percentage of love
