Some properties of the tritide phases formed by the intermetallic compounds Mg2Ni, ZrNi, and LaNi5 have been studied. Whereas ZrNiT3 will retain its stoichiometry indefinitely when sufficient gaseous tritium is available, the stoichiometrics of Mg2NiT4 and LaNi5T6.9 decrease with time. Although all three intermetallic tritides can retain large quantities of the helium-3 tritium decay daughter product in the solid phase, irreversible release of helium begins after several hundred days for ZrNiTx and Mg2NiTx. However, LaNi5Tx retains all of the helium generated in the solid for at least 2400 days. NMR measurements for ZrNiTx and Mg2NiTx imply that helium is retained in microscopic bubbles as previously observed in several binary metal tritides.
