摘要: An investigation on the sinterization of Gd:CeO2 (Ce0.85Gd0.15O1.9−δ ceramic system) 3–10 nm nanoparticles in pressed bodies was done. The heating rate taken as a key parameter and two competing processes were identified, associated with different diffusional mechanisms. Using rates 113 °C min −1 , high-final density (98 % theoretical) obtained by superposing aforementioned mechanisms, resulting homogeneous microstructure at lower temperatures.
