Comparison Of Ball Milling And High Pressure Torsion Processes Of Synthesis Of Nanomaterials

For all nanocrystalline materials prepared by high-energy ball milling synthesis route surface and interface contamination is a major concern in particular mechanical attributed contamination by the milling tools fe or wc as well as ambient gas trace impurities such as o 2 n 2 in rare gases can be problems for high-energy ball milling.

Synthesis of zno nanowires by ball.

Ball-milling and annealing method a two-step process consisting of ball milling and annealing was first developed in 1999 in synthesis of c and bn nanotubes2627 and it has been shown recently as an efficient way to enhance the growth of other one-dimensional nanostructuresThe first step in this method is a mechanical treatment of a.

Also it has been reported that the impact of a high-energy ball milling process sometimes can create a local high temperature above 1000 c 8 andor high pressure up to several gpa9 due to this nature of the ball milling process the process has been used as a mechano-chemical synthesis method 810 for the fabrication of unique.
