The density and surface tension of high-temperature stratifying mixtures of alkali metal bromides and lithium fluoride

Abstract

The density and interphase tension of molten mixtures of lithium fluoride with potassium, rubidium, and cesium bromides were measured in the region of limited mutual solubility by the hydrostatic weighing and meniscus weight methods. The dependences of properties on the size ratio between the mixed ions were determined. The critical order parameters for systems with the predominantly ionic character of interparticle interactions were estimated.
