Abstract

Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Claims

1. A shaped abrasive particle comprising a body including a first surface, a second surface, a side surface extending between the first surface and second surface, and a flange portion extending from the side surface and the first major surface.

2. The shaped abrasive particle of claim 1, wherein the flange comprises a rounded shape.

3. The shaped abrasive particle of claim 1, wherein the flange comprises a length that is less than a length of the body.

4. The shaped abrasive particle of claim 1, wherein the flange has a height that is not greater than a thickness of the body.

5. The shaped abrasive particle of claim 1, wherein the body comprises a single flange and wherein the single flange extends from the body and extends for a distance of not greater than 50% of a total peripheral length of the body.

6. The shaped abrasive particle of claim 5, wherein the single flange extends around at least 1 exterior corner and not greater than 3 exterior corners.

7. A shaped abrasive particle having a body defining a partial-ellipsoid shape, the body including a first surface, a second surface, and a third surface extending between a portion of the first major surface and the second major surface, wherein at least a portion of the first surface and a portion of the second surface are connected to each other along a first edge and wherein a portion of the first surface and a portion of the third surface are connected to each other and define a second edge, and wherein a portion of the second surface and a portion of the third surface are connected to each other and define a third edge.

8. The shaped abrasive particle of claim 7, wherein the first surface comprises a concave shape.

9. The shaped abrasive particle of claim 7, wherein the first surface comprises a planar shape.

10. The shaped abrasive particle of claim 7, wherein second surface comprises a convex shape.

11. The shaped abrasive particle of claim 7, wherein the third surface comprises a concave shape.

12. The shaped abrasive particle of claim 7, wherein the third surface comprises a planar shape.

13. The shaped abrasive particle of claim 7, wherein the first edge comprises a curved or elliptical contour.

14. The shaped abrasive particle of claim 7, wherein the third edge comprises a curved or elliptical contour.

15. A shaped abrasive particle having a toothed body including a plurality of teeth extending from one side of the body, wherein the plurality of teeth define external corners of the body having an average spacing of less than 0.5(L), wherein L defines the length of the body.

16. The shaped abrasive particle of claim 15, wherein each of the teeth of the plurality of teeth comprises a height and wherein at least some of the teeth have a different height compared to other teeth of the plurality of teeth.

17. The shaped abrasive particle of claim 15, wherein each of the teeth of the plurality of teeth comprises a height and wherein all of the teeth have a same height compared to each other.

18. The shaped abrasive particle of claim 15, wherein the plurality of teeth are uniformly distributed around a peripheral surface of the body.

19. The shaped abrasive particle of claim 15, wherein the plurality of teeth are non-uniformly distributed around a peripheral surface of the body.

20. The shaped abrasive particle of claim 15, wherein each of the teeth of the plurality of teeth define a single point on the body.
