| Research Abstract |
Based on controlling of solid-chemical reaction of nano-interfaces through atomistic structure and given external field (such as electric field, stress field and temperature), unique matter transport phenomena (ionic conductivity, densification during sintering, high temperature plastic flow, superplastic behavior, etc.) have been improved in oxide ceramics. Diffusion through the nano-interface and interface energy have been measured, and electric structure has been analyzed in the present study, and consequently, the physical description has been obtained for matter transport phenomena through grain boundary/interface in the oxide ceramics.
