摘要： An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%.

摘要： An abrasive article includes a shaped abrasive particle including a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first end defining an edge between the upper surface and a third side surface, wherein the average difference in height between the first height and the second height is at least about 50 microns. The body also includes a bottom surface defining a bottom area (Ab) and a cross-sectional midpoint area (Am) defining an area of a plane perpendicular to the bottom area and extending through a midpoint of the particle, the body has an area ratio of bottom area to midpoint area (Ab/Am) of not greater than about 6.

摘要： A plurality of particles of abrasive particles, wherein at least 1% of the abrasive particles of the plurality of abrasive particles can have a first shape, wherein the first shape includes a body including a first surface having a rounded contour, a second surface joined to the first surface at a first edge, the second surface having a less rounded contour than the first surface, and a third surface joined to the first surface at a second edge, the third surface having a less rounded contour than the first surface. The plurality of particles can further comprise an average particle size of at least 300 microns and not greater than 900 microns, a specific surface area of at least 0.04 m2/g and not greater than 0.10 m2/g, and an alumina content of at least 65 wt % based on a total weight of the plurality of particles.
