Structure and Physical Properties of Ceramic Materials Based on ZrO-ScO for SOFC Electrolytic Membranes Obtained from Powders of Melted Solid Solutions with a Similar Composition.

This paper presents the results of studying the phase composition, luminescent characteristics, and ionic conductivity of ceramic scandium-stabilized solid solutions of zirconium dioxide containing 9 and 10 mol% ScO. Ceramic samples were prepared by sintering powders obtained by grinding melted solid solutions of the same composition. A comparative analysis of the obtained data with similar characteristics of single crystals has been carried out.
