  • Alumina abrasive particles used for automotive finishing compositions
    Patent number: 11130682
    Abstract: The present disclosure is directed to an alpha alumina powder having a specific surface area, a specific crystallite size, and a specific particle size distribution for use in abrasive polishes, and method of making such powder. The method of making the alpha alumina powder can include calcining an aluminum oxide precursor powder at a temperature of 800-1500° C. and milling the calcined powder to the specific particle size distribution. The alpha alumina powder disclosed herein can quickly enable high removal rate with undiminished aesthetic quality when used in abrasive polishes.
    Type: Grant
    Filed: February 14, 2018
    Date of Patent: September 28, 2021
    Assignee: SAINT-GOBAIN CERAMICS & PLASTICS, INC.
    Inventors: Carlijn Lucinde Mulder, James Berberian, Stephen Bottiglieri, James A. Salvatore
