This strength strongly depends on ceramic bond.
Therefore the process engineers' objective is searching for such structural designs for binders and mechanisms of grain restrain in them, which make it possible for them to be gradually worn, and not torn away from the binder.
Glass is used as ceramic binder for bonding CBN at advanced technological solutions.
