Abstract
The density and thermal expansion coefficients of the Li2Ca intermetallic alloy were measured in the temperature range of 284 - 906 K for the solid and liquid states by means of sample irradiation a narrow gamma-ray beam. The density jump of the Li2Ca intermetallic alloy was also measured during the solid - liquid phase transition. Data on the thermal properties of the alloy above room temperature were apparently obtained for the first time. A table of recommended values of the thermal properties of the Li2Ca alloy over the entire measurement range is presented and their errors are estimated. It is confirmed that the Li - Ca melt with a calcium content of 33.33 at. % is an almost ideal solution.
