Description
Summary:Phase equilibria in the NaF-NaBr-Na 2 MoO 4 and KF-KCl-KBr have been investigated by differential thermal and X-ray powder diffraction analyses. In the NaF-NaBr-Na 2 MoO 4 system, a ternary eutectic and a ternary peritectic, melting and 506 and 570°C with specific enthalpy of melting of 241 and 328 kJ/kg, respectively, have been revealed. In the KF-KCl-KBr system, the existence of zonal solid solutions has been established; crystallization temperatures and melting enthalpies have been determined for samples of several compositions lying on a univariant line.
