Abstract
Composite sintering is a critical fabrication process strongly correlated with an initial performance of solid oxide fuel cells. However, the controlling a composite sintering is still matter of debate because of its inherent complexities of the microstructural evolution during sintering. In this study, we numerically predict the sintering behavior of NiO-YSZ composites using a three-dimensional POTTS Monte Carlo simulation. We show that the green density, grain size distribution, composite volume fraction of the initial composite powder have a great impact on the densification rate and the geometric trajectories during sintering.
