This paper systematically treats the thermochemical properties of binary and complex oxides of the lanthanides and actinides, in terms of other well-characterized species and thermochemical cycles. Since the trivalent lanthanides provide a reference series against which the lanthanide and actinide sesquioxides can be compared, the trivalent-ion energetics are considered first. Recent interest in monoxides, prompted by high-pressure synthesis of lanthanide monoxides and interest in divalent actinide metals and oxides, has led us to include a treatment of the relative stabilities of monoxides and sesquioxides. The important tetravalent state is viewed from the perspective of the dioxides as well as the perovskites BaMO/sub 3/. Since there are no higher-valent lanthanides, systematic trends in pentavalent and hexavalent complex actinide oxides are not treated in this review. 79 references, 10 figures, 4 tables.
