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 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.

Li2Ca金属间合金在固态和液态下的体积性能

用伽玛射线衰减法测定了Li2Ca金属间合金在284 ~ 906 K的固、液相温度范围内的密度和热膨胀系数。测定了Li2Ca金属间合金在固-液相变过程中的密度跃变。首次获得了室温以上合金的体积性能数据。给出了在整个测量范围内Li2Ca合金体积性能的推荐值表，并对其误差进行了估计。证实Li - Ca熔体的钙含量为33.33 at。%几乎是一个理想的解决方案。
