1. A shaped abrasive agglomerate particle comprising shaped abrasive particles bonded in a siliceous matrix, wherein the siliceous matrix comprises a reaction product of at least an alkali silicate and a hardener, and wherein 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, wherein the longest particle lineal dimension is at least twice the shortest particle dimension.
