Volumetric properties of the Li2Ca intermetallic alloy in solid and liquid states

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 gamma-ray attenuation technique. The density jump of the Li2Ca intermetallic alloy was also measured during the solid – liquid phase transition. Data on the volumetric properties of the alloy at above room temperature were apparently obtained for the first time. A table of recommended values of the volumetric 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.
