Agglomerate Size in Precursors and Mechanical Strength of Solid Electrolytes Based on Y2O3-ZrO2, Ce2O3-ZrO2 and Ce2O3-Y2O3-ZrO2 Systems


Precursor powders with controlled average agglomerate size in the range of 40- 12000 nm were synthesized using the reverse precipitation sol-gel. The correlation between the agglomerate size and mechanical strength of the final ceramics synthesized from these precursor powders and the content of Ce3+ and Ce4+ in the precursors was studied using BET, XRD, TEM, PSD, and DSC methods.
