Grain growth in 8 mol% Y 2 O 3 -stabilized zirconia ceramics (8YSZ) under an electric current has been investigated. Enhanced grain growth on the cathode side starts at 1150°C, well below the… (More)
Electro-sintering, i.e., electrically enhanced densification without the assistance of Joule heating, has been observed in 70% dense 8 mol% Y2O3-stabilized ZrO2 ceramics at temperatures well below… (More)
Without sensing any physical force, a neutral object in an ion conducting solid can move in a uniform electrochemical field by coupling a global ion wind with localized counterion diffusion at the… (More)
Migration of residual pores in partially sintered 8 mol% yttria-stabilized zirconia under an electric field was investigated. To avoid shrinkage via sintering, Ar-filled bubbles introduced to dense… (More)
