The process involves extensive ball milling of boron powder for a long period of time up to 150 h in NH 3 gas followed by annealing at high temperature up to 1300°C in N 2 environment It was suggested that a nitriding reaction was induced between boron powder and NH 3 gas due to high energy milling resulting in metastable disordered BN nanostructures and boron nanoparticles
