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.
