Abstract: A shaped abrasive agglomerate particle includes a shaped abrasive particle bonded in a vitreous matrix. The shaped abrasive particles have a longest particle lineal dimension on a surface and a shortest particle dimension perpendicular to the longest particle lineal dimension, and the longest particle lineal dimension is at least twice the shortest particle dimension. The shaped abrasive agglomerate particle has a longest agglomerate lineal dimension on a surface and a shortest agglomerate dimension perpendicular to the longest agglomerate lineal dimension, and the longest agglomerate lineal dimension is at least twice the shortest agglomerate dimension. The abrasive agglomerate particles are useful in abrasive articles. Methods of making the shaped abrasive agglomerate particle and abrading a workpiece are also described.

Abstract: An abrasive agglomerate particle includes fused aluminum oxide mineral bonded in a vitreous matrix. The fused aluminum oxide mineral is present in a range from 70 percent by weight to 95 percent by weight and the vitreous matrix is present at least at five percent by weight, based on the weight of the abrasive agglomerate particle. The fused aluminum oxide mineral has an average particle size of up to 300 micrometers, and the abrasive agglomerate particle has a frusto-pyramidal shape with side walls having a taper angle in a range from 2 to 15 degrees and a dimension of at least 400 micrometers. The abrasive agglomerate particles are useful in abrasive articles. The method includes contacting the workpiece with an abrasive article and moving the workpiece and the abrasive article relative to each other to abrade the workpiece.

Abstract: A structured abrasive article comprises a plurality of shaped abrasive composites disposed on and secured to a major surface of a backing. The shaped abrasive composites comprise magnetizable abrasive particles retained in an organic binder. On a respective basis, each of the magnetizable abrasive particles has a ceramic body with a magnetizable layer disposed on at least a portion thereof. Methods of making and using the structured abrasive articles are also disclosed.
