Patent number: 7497885Abstract: The disclosure relates to fixed abrasive articles having a plurality of three-dimensional abrasive composites including abrasive particles dispersed in a matrix material including a polymeric binder and a plurality of nanoparticulate inorganic filler particles having a volume mean diameter no greater than 1000 nanometers (nm). In some embodiments, the volume mean diameter of the abrasive particles is less than 500 nm, and the volume mean diameter of the inorganic filler particles is no greater than 200 nm. In other embodiments using non-ceria abrasive particles, the ratio of the amount of matrix material to the amount of non-ceria abrasive particles on a volumetric basis is at least 2. In alternate embodiments using non-ceria abrasive particles, the ratio of the amount of non-ceria abrasive particles to the amount of inorganic filler particles on a volumetric basis is no greater than 3. Also provided are methods of making and using fixed abrasive articles according to the disclosure.Type: GrantFiled: February 5, 2007Date of Patent: March 3, 2009Assignee: 3M Innovative Properties CompanyInventor: Jeffrey S.
