概要

• 論文の詳細を見る

• Oxygen partial pressure in equilibrium with nonstoichiometric ceric oxide of a definite composition were determined by equilibration with pure oxygen, air, CO<SUB>2</SUB>, and CO<SUB>2</SUB>-H<SUB>2</SUB> mixtures at 900, 1000, 1100, 1227, and 1300°C, using a thermobalance. The values for the activities and the relative partial enthalpies and entropies of both Ce<SUB>2</SUB>O<SUB>3</SUB> and CeO<SUB>2</SUB> were calculated on the basis of the relation between the <I>P</I>o<SUB>2</SUB> and its composition.
