Abstract
Micro-grains of wurtzite boron nitride(wBN) crystal have been observed in the region of 5.0-7.0 GPa pressure and 1800-2000 K temperature whe re cubic boron nitride has been synthesized in the presence of a catal yst. The wBN grain size is abo ut 20-30 nm. The presence of these micr o-grains indicates that the pressure for wBN growth could be lower tha n that found in the previous work.
