Abstract:
Abrasive particles which are shaped abrasive particles each with an opening is disclosed. The shaped abrasive particles are formed from alpha alumina and have a first face and a second face separated by a thickness t. The opening in each of the shaped abrasive particles can improve grinding performance by reducing the size of a resulting wear flat, can provide a reservoir for grinding aid, and can improve adhesion to a backing in a coated abrasive article.
