| Perovskites are materials of very versatile properties. They may be used in various ways and structures. In this work the results of investigation of the Zr0.84Y0.16Ox electrolyte on La0.6Sr0.4FeO3 perovskite support are presented. The perovskite support was fabricated by iso-axially die-pressing of La0.6Sr0.4 FeO3 powders and sintering at 1150°C. The Zr0.84Y0.16 Ox layer was deposited on La0.6Sr0.4FeO3 by a combination of colloidal suspension and polymer precursor methods. In this way the dense electrolyte layer was prepared at as low temperature as 400°C. This method may be also useful for high-Tc superconductor layers deposition. The chemical interaction between the electrolyte layer and perovskite support was investigated by X-ray diffraction. It was shown that no reaction occurs between cathode and electrolyte until 900°C. Above 1200°C, parameters of the La0.6Sr0.4FeO3 unit cell increase. It suggests that the reaction between Zr0.84Y0.16Ox and La0.6Sr0.4FeO3 is accompanied by substitutional changes in the La0.6Sr0.4FeO3. |
