Sintering Trajectories: Description on How Density, Surface Area, and Grain Size Change

Abstract: Sintering is a mainstay production step in forming metal, ceramic, polymer, and composite components from particles. Since the 1940s, the sintering process is treated using a matrix of mathematical relationships that include at least seven atomic transport mechanisms, several options on powder characteristics, and three pore-grain morphology options. The interplay of these relationships is handled by numerical solutions to predict property development. An alternative approach is to track the sintering trajecto… Show more

“…small particles) after impregnation. Depending on the affinity of CeO 2 for the support and its mobility on the surface upon calcination, sintering of contacting particles leads to larger clusters or agglomerates, where smaller particles sinter more easily than larger particles, 38,39 which results in a broad particle size distribution on the high surface area materials.…”

“…It is most likely that the computational models generated for the simulations contain sharper geometries than those found in the experimental samples, especially in the overlapping areas. Indeed, the reduction in surface energy that happens during the sintering process might minimise the probability of sharp edges in the porous network [39]. The sharper geometries in the models would then induce an early plasticity from excessive stress concentrations.…”
