HYDROGEN STORAGE MATERIALS OF ZIRCONIUM-CHROMIUM-IRON AND OPTIONALLY TITANIUM ALLOYS CHARACTERIZED BY ZRCR2 STOICHIOMETRY

摘要

An alloy consisting of zirconium, chromium, iron and optionally titanium is characterized in having C14 hexagonal crystal structure and ZrCr2 stoichiometry. Members of a preferred class of compounds, represented by the empirical formula Zr1-xTixCr2-yFey wherein "x" has a value between 0.0 and 0.9 and "y" has a value of 0.1 to 1.5, are particularly suitable for use as hydrogen storage materials.
