Abstract

Prediction of density–time curves, i.e., using the sintering curves for one green density to predict those of another during isothermal sintering, was demonstrated for 3 mol% yttria-stabilized zirconia and titania, as well as for data from the literature on various ceramic powder compacts. The predictions utilized only a median green pore size term as the scaling parameter for densification rates between samples of different green densities. Despite the simplicity of the approach, the resulting predictions of density–time curves were in relatively good agreement with the measured data.
