Abstract

To investigate the chemical compatibility of A-site deficient LST anode and stabilized zirconia electrolyte, (La0.25Sr0.75)xTiO3 (x=0.86, 0.88, 0.885, 0.887 and 0.89) powders were prepared by sol-gel method. TiO2 precipitated in each LST sample except LST-0.89. The amount of TiO2 precipitated in A-site deficient LST increased with the increasing of A-site deficiency concentration. Phase change of as-prepared LST and ScSZ composite pellets after annealed at 1200 oC in air was characterized by XRD. Diffusion of Ti from LST into ScSZ at elevated temperature was enhanced with the increasing of TiO2 precipitated in LST. Diffusion of Zr and Sc from ScSZ into LST occurred in LST-0.89/ScSZ, LST-0.887/ScSZ, LST-0.885/ScSZ and LST-0.86/ScSZ pellets. No obvious phase change was observed in LST-0.88/ScSZ, hence LST-0.88 was considered to possess relatively good chemical compatibility with ScSZ.
