抄録

The master sintering curve was applied to nanocrystalline CeO₂ powder compact, and the sintering activation energy was determined to be Q = 405 ± 40 kJ mol⁻¹. A classical model was applied to the initial sintering region and gave Q = 360 ± 30 kJ mol⁻¹. The difference is attributed to the effect of the sintering driving-force between in initial and total sintering stages of nanocrystalline CeO₂ particles. The MSC model can be used to predict the total densification of present powder compact under time-temperature excursion. It is conducted that the MSC is an integral work of the sintering concept that is useful for modelling the densification of CeO₂.
