The methods of physical and chemical analysis was used to study the phase formation in oxide-salty systems and the following conclusions were made: - similarity of crystal structures and small distinction of cation sizes (K+, Rb+, Cs+) in binary systems KNO3 - CsNO3 and RbNO3 - CsNO3 of 2K//A type (K - cation, A - anion) leads to the formation of continuous series of substitutional solid solutions of MX СS1-х NO3 and СSхM1-хNO3 type with a minimum, which indicates complete miscibility of components in a solid state; - the study of phase balances in three-component systems KNO3 - СSNO3 - MoO3 and RbNO3 - СSNO3 - MoO3 made it possible to establish that solid solutions formed in binary systems with the introduction of the third component different in the structure of crystals and ion radius decay in case of MoO3 with the formation of initial components (KNO3, СSNO3, RbNO3); - monovariant lines of co-crystallization (KNO3+СSNO3, KNO3+MoO3; СSNO3+MoO3; RbNO3+СSNO3, RbNO3+MoO3, СSNO3+MoO3 converge in three-component eutectic points; - the surface of a liquidus of the studied three-component systems represents crystallization fields of initial components (MNO3(M - K, Rb, СS), MoO3). The fused electrolysis of these systems can be used to synthesize oxide molybdenum bronze with one or two alkaline metals, but with various structure for each bronze type.
