Improved densification and ionic conductivity in flash-sinteredgamma-ray irradiated yttria-stabilized zirconia Abstract: Experiments on electric field-assisted pressureless sintering were conducted, with a dilatometer connected to a power supply, in zirconia: 8 mol% yttria polycrystalline ceramics exposed […]
Flash Sintering Samaria-Doped Ceria–Carbon Nanotube Composites Abstract: Composite ceramic green pellets were prepared by attrition milling a mixture of (CeO2)0.8(Sm2O3)0.2 (samaria-doped ceria, SDC) ceramic powder and carbon nanotubes (CNTs), followed by uniaxial and isostatic pressing. The […]
Electric field-assisted pressureless sintering gadolinium-, yttrium- and samarium-doped barium cerate Abstract: Gadolinium-, yttrium- and samarium-doped barium cerate compounds were sintered either conventionally at 1500 degrees C or applying an electric field at 1200 degrees C. The […]
Light emission during electric field-assisted sintering of electroceramics Abstract: Electric field-assisted sintering has been shown to occur in ion, electron conducting as well as in insulating polycrystalline ceramics. Considerable linear shrinkage with microstructure control at temperatures lower than […]
AC Electric Field Assisted Pressureless Sintering Zirconia: 3mol% Yttria Solid Electrolyte Abstract: 3 mol% yttria ionic conductors are sintered by applying AC electric fields with frequencies in the 0.5–1.0 kHz range at 1100 °C. The sintering experiments are […]
Electric field-assisted pressureless sintering of zirconia–scandia–ceria solid electrolytes Abstract: Electric field-assisted (flash) pressureless sintering experiments were carried out in ZrO2ceramics doped with 10 mol% Sc2O3 and 1 mol% CeO2 (10Sc1CeSZ). All experiments were conducted isothermally at 1050 °C for 2–5 min with […]
Writers: R. Muccillo, E. N. S. Muccillo Keywords: Flash-sintering; Dilatometry; Impedance spectroscopy; FEG-SEM; Yttria-stabilized zirconia Abstract: Analyses of electrochemical impedance spectroscopy plots and dilatometric curves of ZrO2:Y2O3 (YSZ) green compacts upon sintering show the possibility of choosing the shrinkage level of […]
