Measurements of oxygen potential on uranium-plutonium mixed oxides by means of solid state galvanic cells are discussed and compared with precedent data. Discrepancies in the {Mathematical expression} values at low temperature (1000 K) as well as in the {Mathematical expression} versus T slopes are found, which disappear when the samples are thermally cycled. An analysis is performed of this effect, showing that the absence of a good homogeneization of the sample in oxygen and/or in plutonium content can give rise to mixed potentials and hence to erroneous results. © 1979 Chapman and Hall Ltd.
