Inorganic Materials Aims and scope

Abstract

To assess the nature of variations in the thermodynamic properties of uranium plutonium oxide fuel, which is highly radioactive and toxic, we have measured characteristics of uranium cerium oxides similar in properties to the nuclear fuel. The emf method, a solid electrolyte galvanic cell, and solid-state coulometric titration have been used to find out general trends in the variation of the oxygen potential with the oxygen/metal ratio for U0.718Ce0.282O2 ± x .
