Abstract
The electrical properties of the new fluorite-type phase R0.8Ta0.2O1.7{right angle, 90 degree} ⊥0.3 in the system R2O3-Ta2O5 (R Gd, Y, Er and Yb) were studied. This fluorite phase had a p-type conductivity above 10-3 atm of oxygen partial pressure in the temperature range 650-1250 °C. In the oxygen partial pressure range between 10-4 and 10-21 atm, it showed an ionic conductivity which could occur by the diffusion of oxygen ions through oxygen vacancies.
