Abstract
The protium-absorbing characteristics such as the amount of absorbing protium and the hydrogen reaction have been studied for the LaTMSi, La TMSi, and LaTM2Si2 (TM = Co, Mi) ternary intermetallic compounds. For these compounds, it is found from DSC measurements that only the LaCoS i 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. T he maximum absorbed amount of protium is 0.52 mass% for the LaNiSi all oy.
