  • Patent number: 11478899
    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.
