Similarity of Deuterium Absorption at Room Temperature for Different Ti-Zr-Ni Quasicrystals
Ti-Zr-Ni icosahedral quasicrystals (IQCs) have been regarding as potential hydrogen storage materials due to their high hydrogen ability. Nevertheless, their hydrogen capacities are largely different as reported by different researchers, which is toughly understood.We investigated in this paper deuterium absorption at room temperature for quasicrystalline alloys Ti45Zr38Ni17, Ti41.5Zr41.5Ni17, Ti40Zr40Ni20 with corresponding phase structures of IQC+β(Ti,Zr), IQC+C14(TiZrNi), IQC. The results indicated the same solid solution state for the deuterium in these alloys, whose deuterium concentration was 12~13mmol/g. Given that all these alloys are in a single IQC phase, we believe very similar deuterium capacities for them, which surely needs more strict experimental evidence.
