PURPOSE:To obtain a material for tritium storage and supply capable of storing and releasing gaseous tritium safely in high density, by constituting the above material of an La-Ni-Mn alloy. CONSTITUTION:The material for tritium storage and supply consists of an La-Ni-Mn ternary-system alloy and has a composition represented, preferably, by a general formula LaNi5-xMnx (where x=1-3). This material is capable of storing gaseous tritium safely in high density. The above alloy can easily be obtained by melting raw materials in the prescribed compositional ranges in an inert-gas atmosphere of Ar, etc., by means of a high-frequency furnace or arc melting and is used usually in the form of powder. This alloy powder is extremely easily activated and is capable of adsorbing large amounts of tritium at ordinary pressure and also capable of supplying a tritium gas of about 1atm at a temp. as low as <=about 450 deg.C, and further, this alloy is free from the risk of tritium permeation from the wall of a vessel for tritium.
