Abstract

The evolution of microstructure of the precursor particles during the sintering of ceramic materials has been assessed by a cellular automaton model in which the only physical consideration for the evolution of the system is to minimize the interface energy among the cells and the interface energy alumina-air. The model reproduces qualitatively the vermicular microstructural patterns observed in actual partially-sintered alumina powders for different heat treatments. Moreover, a successful comparison between porosity computed data and experimental data was performed.
