15/06/2012  Advantages of ball milling process: 1. Nanopowders of 2 to 20 nm in size can be produced. The size of nanopowder also depends upon the speed of the rotation of the balls. 2. It is an inexpensive and easy process. Disadvantages; 1. As the process is not so sophisticated, therefore the shape of the nanomaterial is irregular. 2. There may be contaminants inserted from ball and milling additives.15/06/2012  Advantages of ball milling process: 1. Nanopowders of 2 to 20 nm in size can be produced.

Reactive ball-milling (RBM) technique has been considered as a powerful tool for fabrication of metallic nitrides and hydrides via room temperature ball milling. The flowchart shows the mechanism of gas-solid reaction through RBM that was proposed by El-Eskandarany. In his model, the starting metallic powders are subjected to dramatic shear and impact forces that are generated by the ball-milling media.
