1. A shaped abrasive particle comprising:
- a body having (i) a majority content of silicon nitride; and
(ii) a minority content of sintering material including Nd2O3 and Y2O3, wherein the shaped abrasive particle comprises a content (wt %) of Nd2O3 greater than a content (wt %) of Y2O3;
wherein the body of the shaped abrasive particle has a two-dimensional shape as viewed in a plane defined by a length and a width of the body; and
wherein the two-dimensional shape is selected from the group consisting of a polygonal shape, an ellipsoidal shape, a numeral, a Greek alphabet character, a Latin alphabet character, a Russian alphabet character, and a complex shape utilizing a combination of polygonal shapes.
