Significance of crystallochemical factors in chemical reactions into the structure of solids

The chemical reaction of the formation of compounds within the structure of solid as a reaction medium—internal reactions—is the subject of the article. The mechanism of these reactions on the example silicate mineral structure and nanocrystallization of oxide glasses is considered. Local atoms interaction analysis based on the electronegativity of and ionicity of the chemical bonds values helps to understand this mechanism and predict course of intrastructural thermal processes.
