Abstract

Radiation induced change in electrical conductivity of proton conductive ceramics (Yb-doped SrCeO3) have been investigated under 14 MeV fast neutrons in air at temperatures of 293 and 373 K. It was found that the electrical conductivity under neutron irradiation at 293 and 373 K gradually decreased with increased neutron fluence reaching a constant for neutron fluences above 2.0×1018 and 1.0×1017 n/m 2, respectively. The decrease of the electrical conductivity may be associated with annihilation of sub-bands due to Ce4+ to Ce 3+ conversion.
