  • Low Energy Milling to Produce Flake Powders
    Publication number: 20190378660
    Abstract: A method for increasing surface area of a valve metal particle is provided as is an improved valve metal particle provided thereby. The method includes charging a mill apparatus with a valve metal powder and a media wherein the media has an average diameter of at least 0.01 cm to no more than 0.3175 cm. The valve metal powder is then milled at an average kinetic energy of no more than 3,000 ergs per media particle to obtain a milled powder.
    Type: Application
    Filed: July 18, 2019
    Publication date: December 12, 2019
    Inventors: Brady A. Jones, Matthew W. Dufur, James Allan Fife
