Synthesis and colloidochemical properties of cerium dioxide hydrosols stabilized by zirconium polycationic compounds

It is shown that cerium dioxide hydrosols can be stabilized by polycationic compounds of zirconium, and the optimum conditions of the stabilization are determined. Stable CeO2 hydrosols with concentrations of higher than 20 wt % are prepared; the sizes and electrophoretic mobility of their particles, as well as sol stability in the presence of some electrolytes, are investigated. The nature of the aggregation stability of the stabilized cerium dioxide sols is discussed.
