Abstract Pioneering thermodynamic measurements of Mg Pt system are presented. The integral enthalpies of liquid binary alloys were determined using a drop calorimetric method. The obtained results in three independent series were negative in the entire measured concentration range at 1031 K. The studied integral molar mixing enthalpies were compared with the predicted mixing enthalpies based on Miedema's model. The highest difference between the data obtained experimentally and those predicted by the Miedema's model was found to be 3 kJ/mol for xPt = 0.19. Experimental values of liquid Mg Pt solutions were also elaborated with the use of Redlich-Kister polynomial. A very good agreement between measurement data and those calculated by the Redlich-Kister was found.
