Abstract
A shaped abrasive agglomerate particle includes a shaped abrasive particle bonded in a siliceous matrix. The siliceous matrix comprises a reaction product of an alkali silicate and a hardener. The abrasive agglomerate particles are useful in abrasive articles. Methods of making the shaped abrasive agglomerate particle and abrading a workpiece are also described.
Claims20
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.
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, wherein at least one of the shaped abrasive particles or the shaped agglomerate particle has a sloping side wall, and wherein at least one of the shaped abrasive particles or the shaped agglomerate particle has an angle in a range from 95 degrees to 130 degrees between a first face and the sloping side wall.
