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.
