Abstract
The purpose of this work was to study the influence of ultrasonic (US) treatment of zirconium-containing solutions on the characteristics of hydrolytic precipitation of basic zirconium sulfate (BZS), and also on certain properties of BZS and of the zirconium dioxide obtained from it. It was shown that US treatment of zirconium-containing solutions results in depolymerization of polynuclear Zr(IV) complexes, as the result of which precipitation of basic zirconium sulfate from these solutions is more rapid and more complete. The influence of the conditions of US treatment on the particle size has been demonstrated; it is accordingly possible to obtain zirconium dioxide of regulated degree of dispersion from the precipitates.
