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%.

Abstract:
A method of changing the crystallographic orientation of a single crystal body is disclosed that includes the steps of characterizing a crystallographic orientation of the single crystal body and calculating a misorientation angle between a select crystallographic direction of the single crystal body and a projection of the crystallographic direction along a plane of a first exterior major surface of the single crystal body. The method further includes removing material from at least a portion of the first exterior major surface to change the misorientation angle.
