Abstract:
Systems with participation of nitrates and halogenides of alkaline metals find more and more broad practical application.
The four-component mutual system Li, Na // F, Br, NO$_3$ is for the first time described and studied. With the use of innovative methodology of research for the system Li, Na // F, Br, NO$_3$ the model of a tree of phases confirmed experimentally with the DTA method is constructed. The power-intensive threefold eutectic structure of LiF–LiNO$_3$–NaBr with a temperature of melting of 220,8 ${}^\circ$C for application as the medium temperature heataccumulator is revealed.
