  • METHOD OF MAKING A CLOSED POROSITY SURFACE COATING ON A LOW DENSITY PREFORM
    Publication number: 20010001640
    Abstract: A method of making a low density part with a closed porosity surface coating is formed by applying, to a porous powder preform, a coating of powder finer than that of the preform which is sinterable to a near full density below the melting temperature of the powder; and heating the coated preform to sinter the coating to form a near full density, gas impermeable, closed porosity surface coating on the preform.
    Type: Application

  • Method for producing uranium oxide and a non-radioactive fluorine compound from uranium tetrafluoride and a solid oxide compound
    Patent number: 5918106
    Abstract: A method for producing uranium oxide includes combining uranium tetrafluoride and a solid oxidizing agent having a lower thermodynamic stability than the uranium oxide; heating the combination below the vapor point of the uranium tetrafluoride to sufficiently react the uranium tetrafluoride and the oxidizing agent to produce uranium oxide and a non-radioactive fluorine compound; and removing the fluorine compound.
    Type: Grant
    Filed: June 5, 1998
    Date of Patent: June 29, 1999
    Assignee: Starmet Corp.
    Inventors: John B. Bulko, William T. Nachtrab
  • Method for producing uranium oxide and silicon tetrafluoride from uranium tetrafluoride, silicon, and a gaseous oxide
    Patent number: 5901338
    Abstract: A method for producing uranium oxide includes combining uranium tetrafluoride, silicon and a gaseous anhydrous oxidizing agent having a lower thermodynamic stability than any oxide of uranium produced; heating the combination below the vapor point of the uranium tetrafluoride to sufficiently react the uranium tetrafluoride, silicon and the oxidizing agent to produce uranium oxide and a non-radioactive fluorine compound; and removing the fluorine compound.

  • Method for producing silicon tetrafluoride from uranium tetrafluoride
    Patent number: 5888468
    Abstract: A method for producing silicon tetrafluoride includes combining uranium tetrafluoride and silicon dioxide; heating the combination below the melting point of the uranium tetrafluoride to sufficiently react the uranium tetrafluoride and the silicon dioxide to produce non-radioactive silicon tetrafluoride and an oxide of uranium; and removing the silicon tetrafluoride.

  • Light weight, high strength beryllium-aluminum alloy
    Patent number: 5603780
    Abstract: A light weight, high strength ternary or higher-order cast beryllium-aluminum alloy, including approximately 60 to 70 weight % beryllium, one or both of from approximately 0.5 to 4 weight % silicon and from 0.2 to 4.25 weight % silver, with the balance aluminum. Beryllium strengthening elements selected from the group consisting of copper, nickel, or cobalt may be present at from 0.1 to 2.0 weight % of the alloy to increase the alloy strength.
