ABSTRACT:

 the topological structure of the ternary reciprocal system K⁺, Na⁺//F^–, Br^–, NO₃ was studied with the use of the automated research complex . The tree phases were built. The eutectic characteristics  of the secant  triangle NaNO₃–KBr–NaF (eq. %):  84.6 NaNO₃–9.1 KBr–6.3 NaF  were defined at 255.3°C.
