Abstract

The melting of 60CsBr–40KBr–MoBr₃ (mol %) melts was investigated by synchronous thermal analysis and analysis of cooling curves. The concentration dependence of the liquidus temperature of CsBr–KBr–MoBr₃ melts was recorded. It was found that increase of the MoBr₃ concentration from 0 to 16 wt % leads to increase in the liquidus temperature from 841 to 951 K. It was shown that increase of the MoBr₃ concentration from 2 to 16 wt % leads to increase in the relative mass loss of CsBr–KBr–MoBr₃ from 3 to 13 wt %. It was found, that MoBr₃ crystallizes from CsBr–KBr–MoBr3 melt as a separate phase by X-ray phase analysis. Investigation of density of 60СsBr–40KBr–MoBr₃ (mol %) melt was performed by hydrostatic weighing method. It was shown, that increase in the concentration of MoBr₃ from 2 to 8 wt % in CsBr–KBr–MoBr₃ melts result in to increase of density. The density of the 60CsBr–40KBr–MoBr₃ (mol %) melt decreases with temperature. It is shown that the density of melts (60 mol % CsBr–40 mol % KBr)–MoBr₃ (0–8 wt %) varies within 2.69–3.20 g/cm³ in the temperature range 871–1071 K.
