The pressure-composition isotherms for the LaNi3Mn2 -H and D systems were obtained in the temperature range 25–300 C. The absorption plateau pressure increases from 4 Pa at 25 C to 200 kPa at 300 C. Further tests on practical characteristics such as extensive absorption-desorption cycles, the reactivity of the alloy in air, and so on were carried out. The results show that the LaNi3Mn2 alloy may be useful as a candidate for recovery and supply of tritium.
