    Type: Grant
    Filed: January 8, 1991
    Date of Patent: February 25, 1992
    Assignee: Norton Company
    Inventor: Scott W. Pellow
  • Sintered sol gel alumina abrasive filaments
    Patent number: 5009676
    Abstract: A filament shaped sintered alumina based abrasive made up predominantly of fine alpha alumina crystals.
    Type: Grant
    Filed: April 28, 1989
    Date of Patent: April 23, 1991
    Assignee: Norton Company
    Inventors: Charles V. Rue, Ronald H. van de Merwe, Ralph Bauer, Scott W. Pellow, Thomas E. Cottringer, Richard J. Klok
  • Sintered alumina-zirconia ceramic bodies
    Patent number: 4960441
    Abstract: Useful ceramic bodies can be made by mixing zirconia powder with seeded alumina gel, drying, and firing at a high enough temperature to convert the alumina in the gel to microcrystalline alpha alumina. Abrasive grits made in this way, with a zirconia content between 15 and 30 weight percent and at least half the zirconia in the tetragonal crystal form are particularly valuable for use in grinding wheels for snagging steels.
