TL;DR: In this article, the densification of a ceramic powder matrix that contained large macropores of the size much larger than the average grain size of the matrix was studied, and the grain-boundary diffusion controlled sintering models of ceramic matrix contained large Macropores were first established.
Abstract: In this paper, the densification of a ceramic powder matrix that contained large macropores of the size much larger than the average grain size of the matrix was studied. The grain-boundary diffusion controlled sintering models of ceramic matrix contained large macropores were first established. A sintering potential associated with the macropores was also verified and introduced into the models. The experimental data were collected for the sintering of porous 8 mol% yttria-stabilized zirconia system with 20 vol% large pores. The predictions of the model were found in good agreement with experimental data.
