The phase equilibria in the solid state in the system AlVO4−MoO3 were determined by DTA and XRD methods. The experimental results are presented in the form of a phase diagram. In the subsolidus
area, the system AlVO4−MoO3 is a real two-component system only within the range AlVO4−AlVMoO7.

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.
The phase equilibria in the part of the ternary system YPO4–K3PO4–Mg3(PO4)2 over the composition range YPO4–K3PO4–KMgPO4 were examined and determined by differential thermal analysis, X-ray powder diffraction and microscopic analysis in reflected

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.

A diagram of phase equilibria established in a two-component oxide system V25–ZnO has been worked out applying differential thermal analysis and X-ray phase analysis as well as depending on investigations
carried out with the aid of high-temperature X-ray attachment and scanning electron microscope linked to an X-ray microanalyser.
The phase equilibria in that part of the ternary system YPO4−K3PO4−Mg3(PO4)2 which contains the composition range YPO4−KMgPO4−Mg3(PO4)2 were examined and determined by differential thermal analysis, X-ray powder diffraction and microscopic analysis in reflected
Phase equilibria have been established in the solid state in the V9Mo6O40-Cr2O3 system. The results obtained have permitted to state that the system of interest, in the subsolidus area, is not a real two-component system in the whole component concentration range.
Phase equilibria being established in the subsolidus area of the V2O5−Cr2(MoO4)3 system at the whole component concentration range have been studied basing on DTA and X-ray phase powder diffraction. It
has been established that the system is not a real two-component system in the subsolidus area. The fact has been proved by
the presence of fields in that area, where three solid phases remain in mutual equilibrium.
A new calorimetric method and the results of determination of binary systems phase equilibria having a region of phase stratification
on the basis of calorimetric measurements are described in this paper. Isochoric heat capacity temperature dependence of binary
system of hydrocarbon-water has been studied by the method of high-temperature adiabatic calorimeter. Parameters of the phase
stratification region have been determined on the basis of revealed peculiarities of this dependence at phase transitions
liquid-liquid and liquid-vapour and phase diagram have been made.
