Description
A phase diagram from the 1970s does not survive remeasurement, Beata Salamon-Baran and co-authors report in a 2024 study. The system pairs praseodymium bromide with thallium bromide, salts used in scintillator research. Inaccuracies in the old diagram prompted a fresh determination by differential scanning calorimetry. The new results differ significantly from the published version, and the paper discusses where the earlier work went wrong.
Only one congruently melting compound was confirmed in the system, the double salt named in the title. Its heat capacity was characterized across temperature. A CALPHAD assessment checked the internal consistency of the new data. Mixing enthalpy and entropy of the liquid phase were estimated as functions of composition. Inorganic chemists get corrected foundations for crystal growth work.
