Equilibrium liquidus temperatures of binary mixtures from differential scanning calorimetry

Equilibrium liquidus temperatures of binary mixtures from differential scanning calorimetry

The measurements of solid–liquid phase diagrams for a binary mixture using a differential scanning calorimeter are revisited in this paper. A new method employing the DSC curves and a theoretical model to detect solid–liquid equilibrium temperature of the initial mixture before freezing is proposed....

Zusammenfassung:The measurements of solid–liquid phase diagrams for a binary mixture using a differential scanning calorimeter are revisited in this paper. A new method employing the DSC curves and a theoretical model to detect solid–liquid equilibrium temperature of the initial mixture before freezing is proposed. The liquidus temperatures for different compositions are found to be in good agreement with the available literature data.
