  • Cation-enhanced chemical stability of ion-conducting zirconium-based ceramics
    Patent number: 9988312
    Abstract: At least partial substitution of zirconium by hafnium in ion-conducting zirconium-based ceramics provides enhanced chemical stability in alkaline and acid environments.
    Type: Grant
    Filed: March 16, 2017
    Date of Patent: June 5, 2018
    Assignee: National Technology & Engineering Solutions of Sandia, LLC
    Inventors: Erik David Spoerke, Paul G. Clem, Jill S. Wheeler, Leo J. Small, Jon Ihlefeld
  • Electrochemical ion separation in molten salts
    Patent number: 9847149
    Abstract: A purification method that uses ion-selective ceramics to electrochemically filter waste products from a molten salt. The electrochemical method uses ion-conducting ceramics that are selective for the molten salt cations desired in the final purified melt, and selective against any contaminant ions. The method can be integrated into a slightly modified version of the electrochemical framework currently used in pyroprocessing of nuclear wastes.
