The grain growth/densification interaction is known to strongly decrease the shrinkage rate during the final stages of sintering. This phenomenon was studied for α-alumina to provide more accurate sintering models for ceramics. Isothermal interrupted experiments were conducted to identify the parameters of the grain growth law for the model.
