ABSTRACT:
Abrasive grain including manganese oxide therein are provided. The inclusion of manganese oxide can be utilized to reduce the transition temperature of transitional alumina(s) to alpha alumina(s), during the formation of the abrasive grain. Further, manganese oxide presence can be utilized to generate sintered abrasive grain having a submicrometer, faceted microstructure. The abrasive grain are useful in abrasive articles such as coated abrasives, three-dimensional, low density abrasives, and bonded abrasives.
