T. Norby et M. Hartmanova, ELECTRICAL-CONDUCTIVITY AND IONIC TRANSPORT NUMBER OF YSZ AND CR-DOPED YSZ SINGLE-CRYSTALS AT 200-1000-DEGREES-C, Solid state ionics, 67(1-2), 1993, pp. 57-64
Single crystals of YSZ and Cr-doped YSZ with nominally 12 mol% Y2O3 an
d 0.1 mass% Cr2O3 were investigated with respect to ac conductivity an
d ionic transport number at 200-1000 degrees C. Both materials are ion
ic conductors and have temperature dependent activation energies in th
e investigated temperature range.
