  • Ammonia release method for depositing metal oxides
    Patent number: 5372847
    Abstract: A method of depositing metal oxides on substrates which is indifferent to the electrochemical properties of the substrates and which comprises forming ammine complexes containing metal ions and thereafter effecting removal of ammonia from the ammine complexes so as to permit slow precipitation and deposition of metal oxide on the substrates.
    Type: Grant
    Filed: September 16, 1993
    Date of Patent: December 13, 1994
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Gary L. Silver, Frank S. Martin
  • Method for plating with metal oxides
    Patent number: 5340605
    Abstract: A method of plating hydrous metal oxides on at least one substrate, which method is indifferent to the electrochemical properties of the substrate, and comprises reacting metallic ions in aqueous solution with an appropriate oxidizing agent such as sodium hypochlorite or calcium sulfite with oxygen under suitable conditions of pH and concentration such that oxidation and precipitation of metal oxide are sufficiently slow to allow satisfactory plating of metal oxide on the substrate.
    Type: Grant
    Filed: March 5, 1993
    Date of Patent: August 23, 1994
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Gary L. Silver, Frank S. Martin
  • Water treatment method
    Patent number: 5011610
    Abstract: A method for reducing the concentration of any undesirable metals dissolved in contaminated water, such as waste water. The method involves uniformly reacting the contaminated water with an excess amount of solid particulate calcium sulfite to insolubilize the undesirable metal ions, followed by removal thereof and of the unreacted calcium sulfite.
    Type: Grant
    Filed: February 2, 1990
    Date of Patent: April 30, 1991

    Inventors: Frank S. Martin, Gary L. Silver
  • Method for preparing hydride configurations and reactive metal surfaces
    Patent number: 4764228
    Abstract: A method for preparing highly hydrogen-reactive surfaces on metals which normally require substantial heating, high pressures, or an extended induction period, which involves pretreatment of said surfaces with either a non-oxidizing acid or hydrogen gas to form a hydrogen-bearing coating on said surfaces, and subsequently heating said coated metal in the absence of moisture and oxygen for a period sufficient to decompose said coating and cooling said metal to room temperature. Surfaces so treated will react almost instantaneously with hydrogen gas at room temperature and low pressure. The method is particularly applicable to uranium, thorium, and lanthanide metals.
    Type: Grant

    Inventor: Gary L. Silver
  • Method for removing trace pollutants from aqueous solutions
    Patent number: 4572797
    Abstract: A method of substantially removing a trace metallic contaminant from a liquid containing the same comprises,adding an oxidizing agent to a liquid containing a trace amount of a metallic contaminant of a concentration of up to about 10.sup.-1 ppm, the oxidizing agent being one which oxidizes the contaminant to form an oxidized product which is insoluble in the liquid and precipitates therefrom, and the conditions of the addition being selected to ensure that the precipitation of the oxidized product is homogeneous, andseparating the homogeneously precipitated product from the liquid.
