Zirconium oxide gel was prepared by electrochemical reduction of aqueous solution containing zirconium oxychloride octahydrate and zirconium oxynitrate dihydrate. The gel was formed at a Pt electrode below -1.0V (vs. Ag/AgCl). The gel formation by potentiostatic reduction at -1.8V occurred continuously with evolution of hydrogen gas, which caused the gel to drop off from the Pt electrode. It is found that the gel obtained from zirconium oxychloride decomposed to tetragonal zirconium oxide when the freeze-dried gel was heated up to 600°C.
