LiF – NaF – KCl SYSTEM

The stable cross section of LiF - NaF - KCl quadruple mutual system Li, Na, K // F, Cl was studied with the differential thermal (DTA) and X-ray fluorescence (XRF) methods. It was established that in a system the eutectic composition crystallizing at 591 ° C is realized. Temperatures of starting solid-phase reactions were revealed in the ternary systems mutual Na, K // F, Cl and Li, Na // F, Cl, (715 and 650 °C, respectively) corresponding to the con-version of reactants of metastable diagonals into products of stable diagonals.

Key words: eutectic, stable section, mutual system, conversion point, solid-phase reaction, reac-tant, product, state diagram, stoichiometric ratios, non- variant composition
