Description
Summary:The structure of silica activated by different substituents/activators, R sub(n) (Table 1) was analysed by the method of radial distribution functions. The structural parameters of the space configuration of silica were determined beforehand. Fourier analysis of the angular distribution of X-ray radiation supports the existence of a tetrahedral configuration of silicon with respect to oxygen in a silica of the SiO sub(2) + R sub(n) type. The preliminary analysis makes grounds for further quantitative analysis, which permits the construction of a structural model of pure and activated silica with the activators built in it, and quantitative analysis of the local ordering degree in larger areas.
