Chemical Interaction between Perovskite and Super-Ionic
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 electrolyte on perovskite support are presented. The perovskite support was fabricated by iso-axially die-pressing of powders and sintering at 1150°C. The layer was deposited on 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- 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 unit cell increase. It suggests that the reaction between and is accompanied by substitutional changes in the
