Interaction in binary fluoride systems

Abstract

A series of factors affecting the interaction between fluorides is considered. Fluorides are distributed by valence and are arranged in accordance with an increase in the polarizing effect of cations. For eutectic-type melting diagrams, deviations of the experimental liquidus from the ideal one calculated by the Schroder equation are analyzed. In many systems of this type, complex formation is noted in the melts. The most informative factors determining the type of melting diagrams of fluoride systems are refined. Interrelation of various types of melting diagrams is considered.
