  • Method for producing uranium oxide from uranium tetrafluoride and a phyllosilicate mineral
    Patent number: 6153164
    Abstract: A method for producing uranium oxide includes combining uranium tetrafluoride and a phyllosilicate mineral containing a solid oxidizing agent within the mineral's structure 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: October 4, 1999
    Date of Patent: November 28, 2000
    Assignee: Starmet Corporation
    Inventors: John B. Bulko, Bridget M. Smyser
  • Method for producing uranium oxide from uranium oxyfluoride
    Patent number: 6096281
    Abstract: A method for producing uranium oxide includes combining uranium oxyfluoride and a solid oxidizing agent having a lower thermodynamic stability than the uranium oxide after "oxide"; heating the combination below the vapor point of the uranium oxyfluoride to sufficiently react the uranium oxyfluoride and the oxidizing agent to produce uranium oxide and a non-radioactive fluorine compound; and removing the fluorine compound after "compound".
    Type: Grant
    Filed: March 29, 1999
    Date of Patent: August 1, 2000
    Assignee: Starmet Corporation
    Inventors: John B. Bulko, Bridget M. Smyser
  • Method for producing uranium oxide from uranium oxyfluoride and silicon
    Patent number: 6086836
    Abstract: A method for producing uranium oxide includes combining uranium oxyfluoride and silicon and heating the combination below the vapor point of the uranium oxyfluoride to sufficiently react the uranium oxyfluoride and silicon to produce uranium oxide and a non-radioactive fluorine compound; and removing the fluorine compound, e.g. silicon tetrafluoride.

  • Method for producing silicon tetrafluoride from uranium oxyfluoride
    Patent number: 6033642
    Abstract: A method for producing silicon tetrafluoride includes combining uranium oxyfluoride and silicon dioxide; heating the combination below the melting point of the uranium oxyfluoride to sufficiently react the uranium oxyfluoride and the silicon dioxide to produce non-radioactive silicon tetrafluoride and an oxide of uranium; and removing the silicon tetrafluoride.
