N2 - The protium-absorbing characteristics such as the amount of absorbing protium and the hydrogen reaction have been studied for the LaTMSi, LaTMSi2 and LaTM2Si2 (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.
