Abstract
A mechanism of formation and a model of the structure of primary globu les of silica gels prepared in acidic and basic media are proposed. Th e mechanism of formation of the macrostructure of silica gel synthesiz ed at various pH values and the relation between its micro and macro p arameters are discussed. An explanation for the dependence of the text ure characteristics and differences in the silica gel structure on the pH value of the medium is suggested.
