Abstract

A method for obtaining a boron nitride form of density greater than that of hexagonal graphitic boron in the absence of a catalyst, characterized by subjecting a source of boron and a nitrogen source at high pressures and at means of stirring atoms, so that , when at least the pressure and temperature threshold conditions for the transformation into the densest form of recoverable boron nitride are reached, higher density boron nitride from said sources is converted, reducing the pressure and recovering said boron nitride.
