abrasive particles with particular shapes and methods of deformation of such particles

摘要

abrasive particles of particular shapes and methods of deforming such particles an abrasive article including a molded abrasive particle comprising a body having a first height (h1) at a first body end 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 height difference between the first height and the second height is at least 50 microns. the body also includes a bottom surface defining a bottom area (a ~ b ~) and a transverse midpoint area (a ~ m ~) defining an area of a plane perpendicular to the bottom area and extending through a particle midpoint, the body comprising a background area to midpoint ratio (a ~ b ~ / a ~ m ~) of not more than about 6.
