| Abstract | Nanocrystalline CeO2 powders (particle size approximate to 10-15 nm), doped with up to 20 at.-% of Mg, Ca or Y were prepared by chemical precipitation under hydrothermal conditions. The particle size and shape of the powders change slightly with the dopant concentrations. The effect of the dopants on the sintering of the compacted powders was investigated during heating at a constant rate of 10 degrees C/min. The elemental composition and the concentration of the dopant has significant effect on the densification and grain growth. Compared to undoped CeO2, the dopants produce a shift in the densification curve to higher temperatures. For the same dopant concentration and under identical sintering conditions, the Ca doped samples reach nearly full density with the smallest grain size (approximate to 50 nm), however, the Mg doped sample has the lowest density (approximate to 95% of the theoretical) with the largest grain size (approximate to 1 mu m). |
