Abrasive particles having complex shapes and methods of forming same
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%.
1. A shaped abrasive grain comprising:
a body having a first end face, a second end face and a K-shaped first side face extending between the first end face and the second end face.
2. The abrasive grain of claim 1 , wherein the second end face is flat.
3. The abrasive grain of claim 2 , wherein the body comprises a third face extending between the first end face and the second end face, and wherein the third face is flat.
4. The abrasive grain of claim 2 , wherein the body comprises a fourth face extending between the first end face and the second end face, and wherein the fourth face is flat.
5. The abrasive grain of claim 2 , wherein the body comprises an opening extending into the interior of the body.
6. The abrasive grain of claim 5 , wherein the opening extends along a longitudinal axis of the body.
