Abstract
The electrical conductivity of PrxCe1-xO2-delta (PCO) with x less than or e qual to0.05 was examined as functions of praseodymium content (x), oxygen p artial pressure and temperature and a defect model based on multiple oxidat ion states of Pr was found to be consistent with the data. These results ar e used to examine PCOs potential as an active film in gravimetric sensors. (C) 2001 Elsevier Science Ltd. All rights reserved.
