    SOFC composite electrolyte based on LSGM-8282 and zirconia or doped zirconia from zircon concentrate

    The aim of this research is to study zirconia-based electrolyte materials to increase the commercial value of zircon concentrate as a side product of tin mining industries. Synthesis of CaO-Y2O3-ZrO2 (CYZ) and 8mol% Y2O3-ZrO2 (8YSZ) was carried out by solid state reaction. The result shows that ZrO2 presents in tetragonal phase. Doping of Y2O3 into ZrO2 allows a phase transformation from tetragonal into cubic structure with small percentage of monoclinic phase. Meanwhile, doping of CaO-Y2O3 allows a phase transformation into a single cubic phase. These phase transformations enhance the ionic conductivity of the material. Introduction of 10wt% of LSGM-8282 into CYZ (CYZ-L90:10) allows further improvement of inter-grain contact shown by SEM morphological analysis and leads to the enhancement of ionic conductivity.
