Feb 22, 1999 · Ball milling, also called mechanical alloying, is a favorable technique for generation of equilibrium and non-equilibrium materials, like the amorphous or nanocrystalline materials. As pointed out in ref. , the main event in the alloying process is the collision between balls and free powder particles. In the sample obtained by milling for 15 min, lots of carbon onion-like particles were found

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
