Using the method of differential scanning calorimetry, the heat capacity of Mg-Ca alloys containing 10.50, 33.34, and 73.00 at. % Ca, being promising for various practical applications (biocompatible and biodegradable alloys, ultralight construction materials, anode materials, hydrogen absorbent materials, etc.) has been studied experimentally. New reliable experimental results on the specific heat capacity in the temperature range of 190-576.692 K of the solid state have been obtained. The estimated errors of the received data were 2-3 %. The reference tables for temperature dependences of specific heat capacity of Mg-Ca alloys have been compiled. It has been established that over a wide temperature range the heat capacity of solid magnesium-calcium alloys can be estimated with high accuracy using the Neumann-Kopp rule.
