  • Rare earth oxide fluoride nanoparticles and hydrothermal method for forming nanoparticles
    Patent number: 6667019
    Abstract: A hydrothermal method for forming nanoparticles of a rare earth element, oxygen and fluorine has been discovered. Nanoparticles comprising a rare earth element, oxygen and fluorine are also described. These nanoparticles can exhibit excellent refractory properties as well as remarkable stability in hydrothermal conditions. The nanoparticles can exhibit excellent properties for numerous applications including fiber reinforcement of ceramic composites, catalyst supports, and corrosion resistant coatings for high-temperature aqueous solutions.
    Type: Grant
    Filed: September 7, 2001
    Date of Patent: December 23, 2003
    Assignee: Battelle Memorial Institute
    Inventors: John L. Fulton, Markus M. Hoffmann
