Title: MAGNETIZABLE AGGLOMERATE ABRASIVE PARTICLES, ABRASIVE ARTICLES, AND METHODS OF MAKING THE SAME
Abstract:
Magnetizable agglomerate abrasive particle can comprise constituent abrasive particles retained in a binder material. The magnetizable particles and the constituent abrasive particles are unassociated, and wherein the magnetizable particles have a Mohs hardness of 6 or less. Magnetizable agglomerate abrasive particles can also comprise magnetizable abrasive particles retained in a binder material, wherein each magnetizable abrasive particle comprises a respective ceramic body and a magnetizable layer disposed on at least a portion of the ceramic body. Pluralities of abrasive particles are also disclosed. Methods of making, and abrasive articles including the magnetizable agglomerate particles are also disclosed.
