Abstract

We investigated the influence of millimeter-wave irradiation on the cation interdiffusion of ceria/zirconia ceramic couple. The interdiffusion coefficient as well as the moving distance of Matano interface under the millimeter-wave radiation increased in comparison with those under conventional heating method. The activation energy of interdiffusion under millimeter-wave irradiation was found to be lower than that obtained under conventional heating. The intrinsic diffusion for Ce4+ was enhanced, although that for Zr4+ remained almost unchanged. The relative degrees of enhancement could be interpreted by differences in MMW absorptivity between the two ceramics.
