ABSTRACT:
A cubic boron nitride cluster comprises a core (10) and an overgrown region, the overgrown region containing a plurality of cubic boron nitride crystallites (12) extending outwards from the core (10). The majority of the cubic boron nitride crystallites (12) have a cross-sectional area which increases as the distance from the core (10) increases. A method of producing cubic boron nitride clusters is also provided.
