Keywords: colloid silica, time of gel formation, dependence on acid and substrate concentration

Annotation:

Processes of gel formation in acid sols of silica, obtained by solubilisation of silica-alumina, colloid silica and liquid glass in hydrochloric acid are investigated. The equations for dependence of gel formation time on acid and substrate concentration, temperature and mineralization of solutions are obtained. It is shown, that limit stage of gel formation process in acid silica sols is the reaction of silica acid protonation
