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.

Mg2Ca金属间化合物在固态和液态下的热性能

在298.15–1177 K的温度范围内，用大型高温等温液滴量热计测量了固体和液体Mg2Ca金属间合金的焓和热容。焓和热容数据的估计误差分别为0.2%和2%。Mg2Ca金属间合金的熔化焓为483±3J/g。Mg2Ca熔体的热容在993.2–1177 K范围内是恒定的。将获得的结果与文献数据进行了比较。
