Formation Of Nanotubes Ball Milling Method

A solid-state process for formation of boron nitride nanotubes. The formation of boron nitride BN nanotubes via a solid-state process is demonstrated. The nanotubes are produced by first ball-milling hexagonal BN powder to generate highly disordered or amorphous nanostructures, followed by annealing at temperatures up to 1300 C.

Ball Milling Carbon Nanotubes Caesar

Ball milling of graphite and muilti wall carbon nanotubes. Theball-milling of MWCNTs under impact mode usually resulted in the formation of an amorphous phase,whereas that under friction mode induced the fattening of nanotubes. The results showed that a variety of carbon nanomaterials could be obtained by the proper controlling of ball milling.
