Dynamic aspects of cerium dioxide sintering: HT-ESEM study of grain growth and pore elimination
Sintering of CeO 2 is studied by in situ high temperature scanning environmental microscopy (HT-ESEM) at T = 1400 °C. The morphological modifications of a single grains population are recorded for 6 h. Kinetic parameters such as grain boundary velocities are extracted from the obtained image series....

ex situ technique. Using HT-ESEM for sintering study is validated. The grain boundary velocities range between 0 and 5
