Abstract
The objective of physicochemical analysis is to establish the dependence of the properties of an equilibrium system on its parameters. State parameters are typically understood to include composition, pressure, and temperature. These dependencies are expressed in various diagrams, including state-property parameters. In practice, the composition-property diagram is of great importance. Analysis of such a diagram provides information on the nature of component interactions, while the pressure and concentration of components provide information on the composition and stability of the chemical compounds formed in the system. The set of dependencies of all the properties of a uniform system as a function of parameters allows one to graphically depict a phase diagram and a state diagram. To examine each state diagram of a system, the concepts of phase, system, degree of freedom, component, constituent substance, and thermodynamic equilibrium are used.
Many issues related to the electrochemical synthesis of inorganic oxide bronzes are examined and resolved experimentally and in practice.
Based on experimental data for materials with regulated properties, the ISSs are studied. Based on the results of experimental studies, the first promising regions of the phase diagram for the synthesis of molybdenum-vanadium cesium bronzes have been obtained.

ANALYSIS OF TRIPLE RECIPROCAL SYSTEMS BASED ON S1-ELEMENT NITRATES AND HALOGENIDES

Abstract
Currently, the relevance of using more advanced and universal chemicals in the creation of electrolytes of heat carriers of non-melting salt mixtures and thermal batteries is increasing. Based on this, it can be stated with confidence that the halide and nitrate salts of s1-elements have the greatest potential in this direction. When developing the latest generators of electrical and thermal energy, such chemicals have a unique property - the abil-ity to run power plants even at low temperatures. For a wide practical application of melts of halides and nitrates of s1 elements with specified values of thermodynamic characteristics and physico-chemical properties, the study of phase diagrams is required. The method of differential thermal analysis was used to study the phase equilibrium of salt systems of the following type: Li,Rb||I, NO3, Li,K||Br,NO3, Li,K||I,NO3, Li, K||F,NO3, Li, K||Cl,NO3, Li,Rb||Br,NO3, Li,K||Br,NO3, Li,Na||I,NO3, Li,Rb||F,NO3. A comparative analysis of the series of three-component mutual systems formed from the systems experimentally studied by the authors of the article Li,K||F,NO3, Li,K||Cl,NO3, Li,K||Br,NO3, Li, K||I,NO3, Li,Na||F,NO3, Li,Na||I,NO3, Li,Rb||F,NO3, Li,Rb||Br,NO3, Li,Rb||I,NO3,Li,Cs||F,NO3, Li,Cs||Cl,NO3, Li,Cs||I, NO3 and systems studied by other authors Li,Na||Cl,NO3, Li,Na||Br, NO3, Li,Rb||Cl,NO3, Li,Cs||Br,NO3. The considered eutectic compositions of salt systems can be used to create a molten source of RHIT.
