Abstract
Phases present and thermal stability of synthesized hydrides of Mg-TM-H systems (TM = Co and Ni) by preparing under a high pressure of 5 GPa using an anvil-type apparatus were studied. The MgNi2 phase with a novel crystal structure was formed at 1073 K under 5 GPa In addition, for MgH2- Ni system, two novel phases with a new composition of Mg-64 at% Ni, and Mg-55 at% Ni were formed. Using an additional hydrogen source to supply enough hydrogen, the volume fraction of the new phase with a composition of Mg-55 at%Ni increased, and the other phase vanished. This Mg-Ni-H compound was thermally stable up to 498K under an Ar atmosphere of 0.5 MPa.
