Kristallchemische Untersuchungen an den Phasen: (I) Zn(V0,12Nb0,88)2O6, (II) Zn(V0,28Ta0,72)2O6 und (III) Zn(Nb0,58Ta0,42)2O6
Abstract
deEinkristalle der Phasen (I), (II) und (III) wurden mit Vierkreisdiffraktometermethoden untersucht. Phase (I) kristallisiert im Columbittyp, Phase (II) abweichend von beiden ternären Verbindungen (ZnV2O6, ZnTa2O6) im Trirutiltyp. Phase (III) besitzt tri-α-PbO2-Aufbau.

enCrystal Chemistry Examinations of the Phases: (I) Zn(V0.12Nb0.88)2O6, (II) Zn(V0.28Ta0.72)2O6, and (III) Zn(Nb0.58Ta0.42)2O6
Single crystals of the quaternary phases (I), (II), and (III) were prepared by high temperature technique and investigated by X-ray single crystal methods. Phase (I) crystallizes in the columbite Structure. Phase (II) deviates from the ternary compounds (ZnV2O6, ZnTa2O6) and appears in trirutile type. In phase (III) the octahedra arrangement of the tri-α-PbO2 Structure is realized.
