Phasenbeziehungen und Chemischer Transport der Verbindungen im ternären System Re/Mo/O / Phase Relations and Chemical Transport of the Compounds in the Ternary System Re/Mo/O

Abstract

In the ternary system Re/Mo/O four series of mixed oxides have been prepared by heating of powder samples and by transport reactions. The series are derived from the oxides ReO2, MoO2, γ-Mo4O11 und η-Mo4-O11 and have compositions Re1-xMoxO2 (0 < x < 0.37), Mo1-yReyO2 (0 < y < 0.42),γ -Mo4-z1Rez1O11 (0 < z1 < 1), and η-Mo4-z2Rez2O11 (0 < z2 < 1). Contributions to the understanding of the transport mechanism were obtained from thermodynamic calculations. The composition of the mixed crystals obtained have been determined by EPMA and ICP-AES.
