摘要： An abrasive particle can include a coating overlying at least a portion of a core. In an embodiment, the coating can include a first portion overlying at least a portion of the core and a second portion overlying at least a portion of the core, wherein the first portion can include a ceramic material and the second portion can include a silane or a silane reaction product. In a particular embodiment, the first portion can consist essentially of silica. In another particular embodiment, the first portion can include a surface roughness of not greater than 5 nm and a crystalline content of not greater than 60%.

摘要： According to one aspect, an abrasive article includes a backing; a make coat overlying the backing; an abrasive layer comprising abrasive particles and a binder; wherein the abrasive particles comprise a random rotational orientation; wherein the abrasive particles comprise a total height, H, and a fracture feature located at a height of 55%-90% H. The fracture feature is configured to enable fracturing when the particle has a front facing orientation relative to the grinding direction relative to the amount of fracturing when the particle is in a side facing orientation relative to the grinding direction.

摘要： A plurality of abrasive particles can include a coating overlying at least a portion of a core. In an embodiment, the plurality of abrasive particles can include a sintered coating overlying the core, wherein the sintered coating can include an oxide material, and wherein more than 75% of the plurality of abrasive particles are fully covered. In another embodiment, the plurality of abrasive particles can include a sintered coating overlying the core, wherein the sintered coating can include an oxide material, and wherein more the plurality of abrasive particles can have an average coating coverage of greater than 85% of the surface of the core. In an embodiment, the plurality of abrasive particles can include an average coating thickness of not greater than 2 microns. In another embodiment, the plurality of abrasive particles can include a thickness standard deviation of the coating of not greater than 200% of the average coating thickness. In a particular embodiment, the coating can include sintered silica.
