Description
Summary:In this study, hydrated zirconium oxides and yttrium stabilized zirconia powders were synthesized by precipitation. Influence of preliminary solution modification, namely preliminary heating of the solutions and the addition of sulfate ions was investigated. It is shown that the addition of sulfate ions leads to a decrease in the size of aggregates and an increase in the specific surface area of the particles. The greatest increase in the specific surface area was observed during precipitation of a preliminary heated solution with the addition of sulfate ions.
