Diffusion creep is an important deformation mode in ceramics at high temperatures. Although the processes of diffusion creep are well understood in simple metallic systems, there are additional complexities in ceramics because of the presence of two or more ionic species. This paper describes the enhanced role of diffusion creep in ceramics, discusses the effect of antipolar diffusion in simple ceramic systems, and considers diffusion creep in multicomponent ceramics containing two cations.
