It is shown that hydrosols of oxygen-containing compounds of yttrium may be prepared by the peptization and condensation methods. Basic characteristics of hydrosols, such as the size and shape of particles, their phase compositions, electrophoretic mobility, and the pH range of the dispersion medium where sols are stable with respect to aggregation, are determined. Coagulation thresholds of the sols are estimated in the presence of sodium nitrate and sulfate. It is found that the hydrosols coagulate reversibly. Concentration and aging of the sols give rise to the spontaneous formation of slightly structured thixotropic gels. The nature of the aggregation stability of hydrosols is suggested.
