Correlation between the Precursor Dispersity and Mechanical Strength of Solid Electrolytes Based on Ce2O3-ZrO2 System

Precursor powders with the final 9Се₂O₃-91ZrO₂ (mol.%) composition were synthesized using the reverse precipitation sol-gel method varying the concentrations of the solutions of the initial salt reagents. A set of physical and chemical investigation approaches shows that the mechanical strength of Ce-Zr ceramics depends both on precursor dispersity and on CeO₂ content.
