Abstract
A shaped abrasive particle including a body comprising a first major surface, a second major surface, and a side surface extending between the first major surface and the second major surface, the body comprising a sharpness-shape-strength factor (3SF) within a range between about 0.7 and about 1.7 and a Shape Index within a range between at least about 0.01 and not greater than about 0.49.
Claims20
A shaped abrasive particle comprising:
- a body comprising:
- a first major surface,
- a second major surface, and
- a side surface extending between the first major surface and the second major surface,
- wherein the body comprises a two-dimensional shape as viewed in a plane parallel to the first major surface;
- wherein the body comprises a height at a corner, hc;
- wherein the body comprises a height at a midpoint edge opposite the corner, hm;
- wherein the body comprises an interior height, hi, being the smallest dimension of height;
- and
- wherein the body comprises a normalized height difference, (hc-hm)/hi, of at least 0.04.

A shaped abrasive particle comprising:
- a body comprising:
- a first major surface,
- a second major surface, and
- a side surface extending between the first major surface and the second major surface,
- wherein the body comprises a two-dimensional shape as viewed in a plane parallel to the first major surface;
- wherein a first portion of the side surface comprises a first section defining an indentation into the body, the first section extending between a first linear section and a second linear section, wherein the first linear section terminates at a first external corner of the body and the second linear section terminates at a second external corner of the body, and wherein the first section does not intersect the first external corner or second external corner;
- and
- wherein the first section and the first linear section define a first interior corner defining an obtuse angle.
