| Abstract Scope |
It has been reported that sintering densification, as well as high-temperature plastic flow, in oxide ceramics are accelerated by electric field and/or current stimulation. Several groups have recently demonstrated that the acceleration of sintering and high-temperature plastic flow is particularly pronounced under flash event occurring under threshold conditions of temperature and field strength. Both sintering and high-temperature plastic deformation in ceramics are believed to occur primarily through the diffusion of constituent ions. Electric field and current may promote ionic diffusion mainly through the rise in material temperature caused by Joule heating. In this paper, based on recently obtained experimental and theoretical calculation results regarding diffusion under electric fields, non-thermal effects of electric field and current on the sintering and high-temperature plastic flow of oxide ceramics. |
