Abstract: Various embodiments disclosed relate to an abrasive article (10). The abrasive article (10 includes a backing (12) defining a major surface. The abrasive article (10) includes an abrasive layer including a plurality of tetrahedral abrasive particles (16) attached to the backing (12). The tetrahedral abrasive particles (16) include four faces joined by six edges terminating at four vertices (40, 42, 44, 46). Each one of the four faces contacts three of the four faces, and a major portion of the tetrahedral abrasive particles (16) have at least one of the vertices (40, 42, 44, 46) oriented in substantially a same direction.

Abstract: A magnetizable abrasive particle is presented. The magnetizable abrasive particle has a ceramic particle having an outer surface. The magnetizable abrasive particle also has a magnetic coating layer applied to the outer surface of the ceramic particle prior to sintering. The sintered magnetizable particle is responsive to a magnetic field.

Abstract: A surface conditioning article comprises: a fabric backing having first and second opposed major sides: a lofty open nonwoven fiber web comprising entangled fibers disposed on and secured to the first major side of the fabric backing; and abrasive particles secured to the lofty open nonwoven fiber web by a binder material disposed on the first major side. At least some of the entangled fibers extend through the fabric backing from the first side to the second side. At least one raised feature comprising an organic polymer is disposed on a minor portion of the second major side of the fabric backing. The entangled fibers extending through the fabric backing have an average diameter and at least one raised feature has a height of at least 8 times the average diameter. A method of making the surface conditioning article is also disclosed.

Abstract: 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.
