Synthesis of CaO-Y 2O 3-ZrO 2 (CYZ) and 8mol% Y 2O 3-ZrO 2 (8YSZ) was carried out by solid state reaction. The result shows that ZrO 2 presents in tetragonal phase. Doping of Y 2O 3 into ZrO 2 allows a phase transformation from tetragonal into cubic structure with small percentage of monoclinic phase. Meanwhile, doping of CaO-Y 2O 3 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. © 2012 University of Science and Technology Beijing and Springer-Verlag Berlin Heidelberg.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Composite electrolytes,Cubic structure,Doped zirconia,Electrolyte material,Inter-grain,LSGM electrolyte,Monoclinic phase,Morphological analysis,Side products,Single cubic phase,Tetragonal phase[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Ionic conductivity,LSGM electrolyte,Phase transformations,Solid electrolytes,Solid oxide fuel cells (SOFC),Zirconia[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work was supported by the Directorate General of Higher Education, Republic of Indonesia through Hibah Desertasi Doktor and Riset KK ITB.
