This paper is a report on the electrical conductivity properties of ceramic TiO2materials sintered at different temperatures within the range of 1200-1400 °C (1473-1673 K). The measurements were taken in the temperature range 650-1080 °C (923-1353 K) and oxygen partial pressure, p(O2), 10-105Pa. The determined values of the p(O2) exponent differ from those predicted by defect disorder models. This difference allows us to evaluate both electronic and ionic components of the electrical conductivity. Using the Nerst-Einstein equation, the determined ionic component was verified against diffusion data in available literature. The energy gap was determined from both optical and electrical studies. © 2002 Published by Elsevier Science Ltd.
