  • Firing sol-gel alumina particles
    Patent number: 6083622
    Abstract: Sol-gel alumina that is dried but unfired can be explosively comminuted by feeding the dried gel into a furnace held at temperatures above those at which vaporizable materials are eliminated from the particles of gel. At suitably elevated temperatures the firing is sufficient to form fully densified alpha alumina particles of a size suitable for direct use as abrasive grits.
    Type: Grant
    Filed: October 31, 1997
    Date of Patent: July 4, 2000
    Assignee: Saint-Gobain Industrial Ceramics, Inc.
    Inventors: Ajay K. Garg, Arup K. Khaund, Lawrence E. Orne, Mark R. Young
