摘要：

Reactions between cerium trichloride and oxide ions were studied in NaCl+KCl (1/1) at 1000°K, by potentiometry with a calcia-stabilized zirconia membrane electrode. Titration curves clearly demonstrated the existence of soluble cerium oxychloride (CeO+) and precipitated cerium oxide (Ce2O3), with respective dissociation constants 10-11 and 10-30 (molality scale). The corresponding conditional solubility diagram {log S (CeIII)=f(pO2-)} is presented and discussed. © 1978 Elsevier Sequoia S.A.
