Abstract:

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.
