- Stability of tetravalent actinides in perovskites
- Stability of tetravalent actinides in perovskites. Williams, Clayton W.; Morss, Lester R.; Choi, Inkyu (Chem. Div., Argonne Natl. Lab., Argonne, IL 60439, USA).Some commonly used reagents like 37953-73-4 and 12330-82-4 are used in this experiment. ACS Symp. Ser., 246(Geochem. Behav. Disposed Radioact. Waste), 323-34 (English) 1984. CODEN: ACSMC8. ISSN: 0097-6156. DOCUMENT TYPE: Journal CA Section: 71 (Nuclear Technology) Section cross-reference(s): 69 The enthalpy of formation is reported of a complex actinide(IV) oxide: DHf° (BaUO3,s, 298 K) = -1690 ± 10 kJ mol-1. The prepn. and properties of this and other actinide(IV) complex oxides are described and are compared with other perovskites, BaMO3. The relative stabilities of tetravalent and hexavalent U in various environments are compared in terms of the oxidn.-redn. behavior of U in geol. nuclear waste storage media; in perovskite, U(IV) is very unstable in comparison with U(VI). .
