Wurtzite Boron Nitride Crystal Growth in the Region of Cubic Boron Nitride Crystal Synthesizing
-
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 where cubic boron nitride has been synthesized in the presence of a catalyst. The wBN grain size is about 20-30nm. The presence of these micro-grains indicates that the pressure for wBN growth could be lower than that found in the previous work.
