Abstract: Results of turbidimetry study of aggregate stability of binary SiO2–ZrО2 sol and its components in 10–3–10–1 M KCl solutions at рН 3.4 when ZrO2 particles have a high positive charge and SiO2 particles are slightly (close to zero) negatively charged are presented. The ratio of numerical concentrations of sol particles ZrO2 to SiO2 was 7.8 : 1. It was found that in binary SiO2–ZrО2 sol both the process of heterocoagulation (mutual coagulation) of sols and coagulation of the same oxide particles occur throughout the studied range of KCl concentrations. The way of differentiation of processes of dissimilar SiO2 and ZrO2 particles heterocoagulation and coagulation of components is proposed. It is shown that at pH 3.4 the increase in the concentration of KCl solutions in binary SiO2–ZrО2 sol leads to a decrease in the intensity of the process of ZrO2 and SiO2 particles mutual coagulation, which is explained by the decrease in the radius of action of attraction of dissimilar particles.
