摘要
A model to predict the densification and grain growth rates of n -TiO 2 during high pressure/low temperature sintering has been developed and validated by experiments. In this model, densification during intermediate stage sintering is based on a modified grain boundary creep process. For late stage sintering, a modified grain boundary diffusion model that governs atom migration from interparticle boundaries to pores is used. The rate equations for densification during both stages are affected by the increased driving force and decreased diffusivity induced by high pressure. During the sintering process, the concurrent grain growth is modeled through a pore-controlled pinning model, which indicates that grains grow little during the intermediate sintering stage, but experience rapid growth during the final stage.
