Abstract

Phase Relations and Chemical Transport of the Compounds in the Ternary System Re/Mo/O. -Four series of mixed oxides are prepared in the ternary Re/Mo/O system by heating powder samples and transport reactions. Compounds are derived from the oxides ReO 2 , MoO 2 , γ-Mo 4 O 11 and η-Mo 4 O 11 and show compositions Re 1−x MoxO 2 (0 ¡ x ¡ 0.37), Mo 1−y ReyO 2 (0 ¡ y ¡ 0.42), γ-Mo 4−z1 Re z1 O 11 (0 ¡ z 1 ¡ 1), and η-Mo 4−z2 Re z2 O 11 (0 ¡ z 2 ¡ 1). Contributions to the understanding of the transport mechanism are obtained from thermodynamic calculations. -(FELLER, J.; OPPERMANN, H.; KUCHARKOWSKI, R.; DAEBRITZ, S.
