Abstract
A cellular automata model of composite ceramic material is established which containing sintering additives and pores based on grain boundary energy theory and grain growth boundary curvature driving force theory; then the sintering densification process of ceramic material is simulated. The results show that the density of ceramic material containing sintering additives is higher than the ceramic material without sintering additives, and the grain growth index is lower in the condition of containing sintering additives than without sintering additives. The sintering additives have obvious roles to improve the ceramic material density and get smaller grains. The simulation results are very close to the microstructure of Al2O3/TiN ceramic material, the results show that the cellular automata model is applicable to the research of ceramic materials sintering densification process containing sintering additives.
