The article investigated the preparation of sol-gel paste from many component substances barium chloride (BaCl2), strontium chloride (SrCl2), antimony trioxide (Sb2O3), citric acid in a liquid medium by the complexometric (chelate) method. During the reaction, the pH of the medium was 5.5 units, temperature conditions 40–42 °C. For efficient complex formation, an electric mixer was used. The ratio of multicomponent substances was according to the following formula BaIx ∙ SrIx ∙ SbIx ∙ CAIx (where X = I:I:I:I). This reaction was studied, complexes with metal ions. Thus, the sol-gel process includes hydrolysis at temperature conditions, and the mechanical effects of the latter processes occur during further polymerization and a viscous resin (gel) is formed. A homogeneous white paste is obtained, which is nanosubstances.
