Abstract

Abrasive particles comprising shaped abrasive particles each having a sloping sidewall, each of the shaped abrasive particles comprising alpha alumina and having a first face and a second face separated by a thickness, t. The shaped abrasive particles further comprising either: a draft angle α between the second face and the sloping sidewall, and the draft angle α is between about 95 degrees to about 130 degrees, or the sloping sidewall having a radius, R, between the first face and the second face and the radius, R, is between about 0.5 to about 2 times the thickness, t.
