High Energy Ball Milling Process

High-Energy Ball Milling - an overview | ScienceDirect Topics

High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.

High energy ball milling process for nanomaterial synthesis

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.
