ABRASIVE PARTICLES

A method of making a formed ceramic abrasive particle is presented that includes molding a dispersion of a ceramic abrasive particle precursor mixture. The method also includes drying the molded dispersion to form a ceramic abrasive particle particle precursor. The method also includes calcining the ceramic abrasive particle precursor. The method also includes sintering the ceramic abrasive particle precursor to form the formed ceramic abrasive particle. The method also includes impregnating the ceramic abrasive particle precusor with a mixture. The mixture includes one or more of a first group consisting of: an oxide of yttrium, praseodymium, samarium, ytterbium, neodymium, lanthanum, gadolinium, dysprosium, and erbium or one or more of a second group consisting of: oxide of iron, magnesium, zinc, silicon, cobalt, nickel, zirconium, hafnium, chromium, cerium, titanium. Impregnating the ceramic abrasive particle precursor occurs after drying, calcining or sintering.
