Claims20
A composition comprising:
- a plurality of abrasive particles comprising alumina, wherein the plurality of abrasive particles comprise mesoporosity having an average meso branching index of at least 55 junctions/microns2 and a median particle size (D50) of at least 5 microns.
A composition comprising:
- a plurality of abrasive particles comprising alumina, wherein the plurality of abrasive particles comprise a porosity of at least 5 vol % and a half 100 percent distribution value (D100-D0)/D50 of not greater than 7.5.
A method for conducting a material removal process on a workpiece comprising:
- moving a plurality of abrasive particles relative to a workpiece, the plurality of abrasive particles comprising alumina and further comprising at least one of:
- a) an average meso branching index of at least 55 junctions/microns2 and a median particle size (D50) of at least 5 microns;
- b) a porosity of at least 5 vol % and a half 100 percent distribution value (D100-D0)/D50 of not greater than 7.5;
- or
- c) any combination thereof.
