Abstract
Ceria-stabilized zirconia is a potential MHD electrode material because of its refractoriness, oxidation and corrosion resistance, as also adequate electrical conductivity at operating temperatures. The sintering behaviour of 80 m/o Zr02-20 m/o Ce02 and 80 m/o Ce0,-20 m/o Zr02 has been investigated in air and vacuum in the temperature range of 1300"-1600C. Nb20, and Ta20 5 additions were both found to improve densification. Room temperature electrical conductivity improved considerably when sintering was carried out in vacuum and values of the order of to- (ohm-cm)-1 were obtained.
