Synthesis and properties of CaZrO3 films on YSZ electrolyte surface

CaZrO3 films are studied that were obtained on ceramic supports of solid electrolyte of ZrO2 + 9 mol % Y2O3 (YSZ, yttria stabilized zirconia) from alcohol solutions of zirconium oxychloride and calcium nitrate using the method of dipping with the following drying and annealing. The thickness and morphology of films depend on the concentration of the film-forming solution. Vickers microhardness of the CaZrO3 films was determined. The impedance spectroscopy method was used to study conductivity of films at the temperature of 400-600A degrees C by comparison of impedance spectra of clean supports and supports with a film coating.
