Dynamic aspects of cerium dioxide sintering: HT-ESEM study of grain growth and pore elimination
Graphical abstract summary: 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 hours. Kinetic parameters such as grain boundary velocities are extracted from the obtained image series. An intragranular surface pore elimination process is observed. ABST...
متن کاملPorosity and Pore Size Distribution
A soil’s porosity and pore size distribution characterize its pore space, that portion of the soil’s volume that is not occupied by or isolated by solid material. The basic character of the pore space affects and is affected by critical aspects of almost everything that occurs in the soil: the movement of water, air, and other fluids; the transport and the reaction of chemicals; and the residen...
متن کاملGrain size, size-distribution and dislocation structure
Diffraction peak profile analysis (or Line Profile Analysis, LPA) has recently been developed to such an extent that it can be applied as a powerful method for the characterization of microstructures of crystalline materials in terms of crystallite size-distribution and dislocation structures. Physically based theoretical functions and their Fourier coefficients are available for both, the size...
متن کاملSintering and yttrium grain boundary segregation in sub-micron grain size alumina
Sintering behavior with and without external stress was investigated using undoped and doped (1500 ppm yttria) sub-micron a-alumina powders. The yttria doped alumina showed anomalous behavior with grain size around 0.9 pm, a second peak in densification rate during free sintering and a stagnation followed by a steep increase in flow stress during sinter forging. These were thought to correspond...
متن کاملThe effects of sintering temperature and duration on the flexural strength and grain size of zirconia
Objective: This study investigated the effect of different sintering temperatures and times on the flexural strength and grain size of zirconia. Material and methods: Zirconia specimens (In-Coris ZI, In-Coris TZI, 120 samples) were prepared in a partially sintered state. Subsequently, the specimens were randomly divided into three groups and sintered at different final sintering temperatures an...
