    Feb 03, 2012 Multiwalled boron nitride nanotubes were produced in high yield by Jun Yu et al[113] by using a ball milling-annealing method. These thin boron nitride nanotubes with a diameter less than 10 nm were produced by ball milling-annealing method in which amorphous boron was first ball-milled for 150 h in a NH 3 atmosphere and subsequently annealed

    The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling balls in the bowl
