Abstract

ZrO₂ powder was prepared by ultrasonic spray pyrolysis with H₂O₂ addition. Powders prepared by zirconyl oxychloride showed a spherical shape and many shell fragments, while the shell fragments disappeared with the addition of H₂O₂ to the precursor solution. The precursor solution was dried and DTA/TG was performed for the residues in order to investigate the effects of H₂O₂. The results show that H₂O₂ changed the decomposition procedures of the precursor solution.
