Conductivity of SrTiO3 based oxides in the reducing atmosphere at high temperature

The conductivities of several donor-doped SrTiO3 based oxides, which were prepared in air, were studied in a reducing atmosphere at high temperature. The conductivities of all specimens increased slowly with time at 1000 deg C in 9% H2/N2, even after 100h. Nb-doped SrTiO3 showed relatively fast redu...
