Abstract
The enthalpy and heat capacity of solid and liquid Mg2Ca intermetallic alloy were measured by massive high-temperature isothermal drop calorimeter over the temperature range of 298.15–1177 K. The estimated errors in the data on enthalpy and heat capacity were 0.2 % and 2 %, respectively. The fusion enthalpy of the Mg2Ca intermetallic alloy was determined to be 483 ± 3 J/g. The heat capacity of the Mg2Ca melt was shown to be constant in the range of 993.2–1177 K. A comparison of the obtained results with literature data has been carried out.
