It is studied the influence of metal salts complexes charge value on its association at the ethyl silicate sol and reactivity in presence of polysilicic acid micelles by different degree of its condensation. It has been theoretically founded the possibility of water volume reduction during the hydroxide precursors obtaining for sol-gel compositions by mentioned system. The results of investigations are successfully used for elaboration of multipurpose powders: modified fillers of stomatological plastic masses, sintering and modifying additives for refractory concrete and constructional ceramics.
