Abstract
The effect of sonication on the composition and properties of zirconia precipitated from aqueous zirconyl nitrate solutions at various pH values has been studied using thermal analysis, X-ray diffraction, and low-temperature nitrogen adsorption measurements. The results demonstrate that acoustic processing considerably reduces the content of sorbed ions in amorphous ZrO2 · xH2O gels and allows one to control the composition and microstructure of the nanocrystalline zirconia produced through thermal decomposition of the gels.
