研究了LaTMSi、LaTMSi2和LaTM2Si2(Tm=Co，Ni)三元金属间化合物的吸钚特性，如吸铂量和氢反应等。对于这些化合物，从DSC测量中发现，只有LaCoSi和LaNiSi化合物在高温下发生氢化物反应。LaCoSi合金在457K发生歧化反应，而LaNiSi合金在425K可逆地吸附和解吸Pr，最大Pr吸入量为0.52质量%。
The protium-absorbing characteristics such as the amount of absorbing protium and the hydrogen reaction have been studied for the LaTMSi, LaTMSi 2 and LaTM 2 Si 2 (TM=Co, Ni) ternary intermetallic compounds. For these compounds, it is found from DSC measurements that only the LaCoSi and LaNiSi compounds show hydride reactions at elevated temperatures. The LaCoSi alloy has a disproportionation reaction at 457 K, whereas the LaNiSi alloy reversibly absorbs and desorbs protium near 425 K. The maximum absorbed amount of protium is 0.52 mass% for the LaNiSi alloy.
