Abstract
Simultaneous measurements of electrical conductivity and thermoelectric power of 1 mol% InO 1.5 doped CaZrO 3 were made at 1523, 1473, 1373 and 1273 K under oxygen partial pressure, P O 2 , between 10 −14 and 1 atm using dried O 2+Ar and CO+CO 2 gas mixtures. InO 1.5 doped CaZrO 3 was found to be the hole–oxide ion mixed conductor under a dry atmosphere. The partial conductivity of holes was predominant in the high P O 2 region and was proportional to P 1/4 O 2 . The partial conductivity of oxide ions without p O 2 dependency was predominant in the low p O 2 region. Partial thermoelectric powers of holes and oxide ions were theoretically evaluated from the total thermoelectric power measurements, and the electrical transport properties of holes, i.e. the mobility of holes was estimated using so-called Jonker's analysis. The present results suggest the comparable concentration of holes with calcia stabilized zirconia and the higher mobility of holes in CaZr 0.99In 0.01O 2.995.
