  • Purification of barium ion source
    Patent number: 8845993
    Abstract: A method of preparing purified barium nitrate includes precipitating barium nitrate crystals from a solution, and washing the barium nitrate crystals with an aqueous solution including at least 10 wt % nitric acid.
    Type: Grant
    Filed: January 20, 2011
    Date of Patent: September 30, 2014
    Assignee: EEStor, Inc.
    Inventors: Lucas Pettey, Richard D. Weir
  • Selective-cation-removal purification of aluminum source
    Patent number: 8287826
    Abstract: A method of purifying an aluminum source includes dissolving an aluminum ion source to provide a first solution including aluminum ions having a pH of not greater than 4.0, adjusting the pH of the first solution with a tetraalkylammonium hydroxide solution to a pH in range of 4.1 to 8.4 thereby forming an aluminum hydroxide precipitate, separating the aluminum hydroxide precipitate from the first solution, washing the separated aluminum hydroxide precipitate with an aqueous solution having a pH in a range of 4.1 to 8.4, dissolving the washed aluminum hydroxide precipitate using an acid to provide a second solution having a pH of not greater than 4.0, and forming an aluminum salt from the second solution.
    Type: Grant

    Assignee: EEStor, Inc.
    Inventor: Lucas Pettey
  • OXIDE COATED CERAMIC POWDERS
    Publication number: 20110244123
    Abstract: A method of forming a dielectric powder includes depositing a metal nitrate coating on ceramic particles to form nitrate coated ceramic particles, separating the nitrate coated ceramic particles, dewatering the nitrate coated ceramic particles, and heat treating the nitrate coated ceramic particles at a temperature sufficient to convert the metal nitrate to a metal oxide, forming metal oxide coated ceramic particles.
