  • Hydrogen storage materials of CeNi.sub.5-x Mn.sub.x alloys
    Patent number: 4663143
    Abstract: A ternary alloy comprised of cerium, nickel and manganese is characterized in having CaCu.sub.5 hexagonal crystal structure and stoichiometry. Members of a preferred class of compounds, represented by the empirical formula CeNi.sub.5-x Mn.sub.x wherein "x" has a value between 0.1 and about 1.0. These alloys react with hydrogen readily and can absorb a large amount of hydrogen at moderate pressure and temperature and are particularly suitable for use as hydrogen storage materials.
    Type: Grant
    Filed: December 21, 1983
    Date of Patent: May 5, 1987
    Assignee: Koppers Company, Inc.
    Inventors: William E. Wallace, Faiz Pourarian
  • Hydrogen storage materials of zirconium-chromium-iron and titanium alloys characterized by ZrCr.sub.2 stoichiometry
    Patent number: 4556551
    Abstract: An alloy consisting of zirconium, chromium, iron and optionally titanium is characterized in having C14 hexagonal crystal structure and ZrCr.sub.2 stoichiometry. Members of a preferred class of compounds, represented by the empirical formula Zr.sub.1-x Ti.sub.x Cr.sub.2-y Fe.sub.y 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.
    Type: Grant
    Filed: March 22, 1984
    Date of Patent: December 3, 1985
    Assignee: Koppers Company, Inc.
    Inventors: William E. Wallace, Faiz Pourarian
  • Hydrogen storage materials of hyperstoichiometric alloys
    Patent number: 4512965
    Abstract: Quaternary hyperstoichiometric alloys of the formula: ZrCrFeT.sub.x and their hydrides are provided, characterized as having MgZn.sub.2 hexagonal crystal structure wherein T is selected from Mn, Fe, Co, Ni and Cu, and X is a number from 0.1 to 1.0. These alloys readily form hydrides at low hydrogen pressure and are suitable for use as hydrogen storage materials.
