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"-1600°C. 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.
