Abstract
In this paper, the possibility of obtaining manganese dioxide hydrosols by condensation in the presence of sodium thiosulfate is considered. The main properties of hydrosols, including particle size and shape, phase composition, electrophoretic mobility, and the pH range of the dispersion medium in which sols are aggregatively stable, are determined. The sol coagulation thresholds in the presence of potassium chloride, sodium sulfate, and potassium sulfate were determined. It was found that the hydrosols coagulation is reversible. The nature of the aggregative stability of obtained manganese dioxide sols is discussed.
