  • Patent number: 9410063
    Abstract: A polishing slurry can include zirconia particles. The polishing slurry can be used to polish conductive and insulating materials, and is particularly well suited for polishing oxide materials as well as metals. The characteristics of the zirconia particles can affect the polishing of workpieces. By selecting the proper characteristics, the polishing slurry can have a good material removal rate while still providing an acceptable surface finish. The zirconia particles can be used as a replacement for, or in conjunction with, ceria or other abrasive particles. The content of zirconia particles in the polishing slurry may be less than a comparable polishing slurry having silica or alumina particles.
    Type: Grant
    Filed: July 15, 2015
    Date of Patent: August 9, 2016
    Assignee: SAINT-GOBAIN CERAMICS & PLASTICS, INC.
