CATHODIC ELECTROSYNTHESIS OF CERAMIC DEPOSITS

Cathodic electrosynthesis of TiO2, ZrO2 and ZrTiO4 deposits on platinu m substrates was performed via hydrolysis of TiCl4 and ZrOCl2 salts di ssolved in a mixed methanol-water solvent in presence of hydrogen pero xide by an electrogenerated base. The deposits were characterized bq, XRD, TG/DTA, SEM ann EDS. Deposits as obtained were amorphous. The cry stallization behaviour of the deposits has been studied Crystallite si zes were derived at different temperatures from X-ray broadening data. A possible mechanism of electrosynthesis ann the role of hydrogen per oxide are discussed.
