ABRASIVE GRIT COMPRISING FIRST SURFACE WITHOUT CORNER AND SECOND SURFACE WITH CORNER

摘要

An abrasive grain includes a surface having at least a first face with a first outline, and at least one second face with a second outline. The first outline does not contain any vertices, but the second outline contains at least one vertex. The abrasive grain may include a ceramic material, especially polycrystalline α-Al2O3.
