Synthesis and powder X-ray diffraction analysis of new mixed rare-earth and selenium oxychlorides with composition LnSeO3Cl
A series of new mixed rare-earth and selenium oxychlorides with composition LnSeO3Cl (Ln = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, or Y) were prepared by annealing together LnOCl and SeO2 in sealed silica tub...

Crystal Structure and SHG Characterization of γ-BiSeO3Cl
γ-BiSeO3Cl crystals were grown and characterized by x-ray microanalysis and second harmonic generation. The structure of γ-BiSeO3Cl was determined by single-crystal x-ray diffraction: sp. gr. Pna21, a = 11.707(4)...

Thermochemical investigation of Re2O3—SeO2 systems: III. Yttrium selenium oxides in the pseudo-binary system
Ternary pure phases in the thermodynamical equilibrium Y2SexO3+2x in the pseudo-binary Y2O3-SeO2 system have been synthesized by solid state reactions and characterized by X-ray powder diffraction, IR spectroscop...

Zustandsbarogramme — Zustandsdiagramme durch Gesamtdruckmessungen
From phasebarograms it is possible to construct phase diagrams. We show on example of the system Bi/Se/O how follow ternary sections from the total pressure measurements in equilibrium and how we can attribute...

Investigation of the phase barograms and diagrams of the GeI4-I2, GeI4-BiI3 and GeI4-HgI2 systems
The phase barograms of the systems GeI4-I2, GeI4-BiI3 and GeI4-HgI2 were determined by total pressure measurements in a membrane zero manometer and the resulting phase diagrams were compared with those obtained b...
