ABSTRACT:
An improved process for converting hexagonal boron nitride (HBN) particles into cubic boron nitride (CBN) in a high pressure/high temperature apparatus (HP/HT) is disclosed. More specifically, by using melamine as a catalyst, operating pressures and temperatures as well as catalyst costs, may all be reduced.
