Abstract
Official abstract text for this publication.
An abrasive article includes a shaped abrasive particle including a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first end defining an edge between the upper surface and a third side surface, wherein the average difference in height between the first height and the second height is at least about 50 microns. The body also includes a bottom surface defining a bottom area (A b ) and a cross-sectional midpoint area (A m ) defining an area of a plane perpendicular to the bottom area and extending through a midpoint of the particle, the body has an area ratio of bottom area to midpoint area (A b /A m ) of not greater than about 6.
First claim
Opening claim text (preview).
What is claimed is: 1. An abrasive article comprising: a shaped abrasive particle comprising a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first end defining an edge between the upper surface and a third side surface, wherein the body comprises a normalized height difference defined by the equation [(h1−h2)/(h…
