Oxygen vacancy plays an important role in the flash sintering (FS) process. In defect engineering, methods to create oxygen include doping, heating, and etching, all of them often have complex process or equipment. this study we used dielectric barrier discharge (DBD) as a new engineering technology increase concentration green billet with different ceramics (ZnO, TiO2 3 mol% yttria-...

The electrochemical reactions of hydrogen oxidation and steam reduction have been investigated for a porous cermet electrode made Ni 3YSZ. characterizations performed over large range gas compositions at 700°C. It has shown that the fuel response is activated by potential under anodic current while limiting density appears cathodic polarization. Moreover, impedance diagrams exhibit shape repres...

Flash sintering is one of the newest techniques for sintering ceramics to near full density. It occurs in an appropriate combination of temperature and electric field. Temperature measurement is one of the most serious challenges in this process. In the present study, we tried to model a flash sintering process of 8YSZ and 3YSZ with finite element method to make an assessment for temperature di...
