Abstract
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%.

13. A shaped abrasive particle comprising:
a generally prismatic body having a length, width, and thickness; wherein the length is greater than the width and the length is greater than the thickness; wherein the generally prismatic body with a first end face and a second end face have a polygonal shape; and wherein the generally prismatic body comprises a center of mass and a geometric midpoint and wherein the center of mass is displaced from the geometric midpoint by a distance selected from the group consisting of;
(Dh) of at least about 0.05(h) along a vertical axis of the body defining the height, (Dw) of at least about 0.05(w) along a lateral axis of the body defining the width, and (Dl) of at least about 0.05(l) along a longitudinal axis of the body defining the length.- View Dependent Claims (14, 15, 16)
