Abstract:
Shaped abrasive particles comprising alpha alumina and having a first side, a second side, a maximum length along a longitudinal axis and a maximum width transverse to the longitudinal axis. The first side comprising a quadrilateral having four edges and four vertices with the quadrilateral selected from the group consisting of a rhombus, a rhomboid, a kite, or a superellipse. The shaped abrasive particles having an aspect ratio of the maximum length divided by the maximum width of 1.3 or greater.
