Abstract
The phase transformation of amorphous boron nitride (aBN) into the cub ic modification (cBN) in the presence of magnesium boron nitride has b een studied in a wide range of pressures and temperatures. The minimum pressure of cBN formation was found to be 2.5 GPa at 2100 K. This is the lowest pressure for cBN crystallization employing the catalyst-sol vent process and is reported here for the first time.
