  • Method of making zirconia-containing nanoparticles
    Patent number: 8808549
    Abstract: A method of preparing zirconia-containing nanoparticles and a method of preparing a composite material that includes the zirconia-containing nanoparticles are provided. A method of treating a zirconium carboxylate salt solution to remove alkali metal ions and alkaline earth ions is provided. The treated solution can be used as a feedstock to prepare the zirconia-containing nanoparticles. Additionally, a continuous hydrothermal reactor system is provided that can be used, for example, to prepare the zirconia-containing nanoparticles.
    Type: Grant
    Filed: November 1, 2013
    Date of Patent: August 19, 2014
    Assignee: 3M Innovative Properties Company
    Inventors: Brant U. Kolb, Danny B. Anderson, Robert S. Davidson, Mark J. Hendrickson, James J. Leach, Taun L. McKenzie
