Abstract  

A diagram of the phase equilibria established in the solid state in the system FeVO4−Fe2WO6 was plotted on the basis of X-ray phase analysis and DTA. This system, one of the intersections of the three-component system Fe2O3−V2O5−WO3, does not appear to be a real two-component system in the solid state.

Abstract  

Phase equlibria in the solid state in the system Fe2WO6−Fe8V10W16O85 were studied by means of X-ray phase powder diffraction and differential thermal analysis, This system is one of the intersections of the three-component system Fe2O3−V2O5−WO3. The investigation demonstrated that the system is not a real two-component system even below the solidus line.

Abstract  

Phase equilibria up to the solidus line in the system Fe2O3−Fe8V10W16O85 were determined by means of X-ray phase powder diffraction and differential thermal analysis. This system is one of the intersections of the three-component system Fe2O3−V2O5−WO3. The studies revealed that this is not a real binary system, even in the solid state.

Abstract  

Phase equilibria in subsolidus area in the ZnO-V2O5-Fe2O3 system have been investigated over the whole concentration range of the oxides. The components of this system form two compounds: Zn2FeV3O11 and Zn3Fe4(VO4)6. A solidus area projection onto the component concentration triangle plane of the ZnO-V2O5-Fe2O3 system has been constructed using DTA and XRD methods. 11 subsidiary subsystems can be distinguished in this system. Melting temperatures of mixtures of solid phases coexisting at equilibrium in each of subsidiary subsystems were determined.

Abstract  

The phase equilibria established up to the solidus line in the system Fe2V4O13−WO3, one of the intersections of the three-component system Fe2O3−V2O5−WO3, have been studied. The system appears not to be a real two-component system.

Abstract  

Phase equilibria being established in the solid state in the system V2O5−Fe8V10W16O85 were examined by X-ray phase powder diffraction and DTA. It has been found that the system of interest is a real two-component system with an eutectic temperature 6205C.
