Influence of ball milling parameters on the particle

2010-1-1  Lead free BT nanocrystalline powders with average particle size as small as 16 nm have been produced by high-energy ball milling. With increasing speed of the ball mill from 200 to 400 rpm at a fixed milling time of 30 h, the particle size of the milled powders decreases gradually till it reaches a saturation value. This observed result agrees

Ball milling: a green technology for the preparation

Ball milling was performed for 24 hours at 1000 rpm. With this pre-treatment, the resulting nanocrystals had a spherical shape with a 100–200 nm diameter and a 3–7 nm height, rather than a rod-like shape. This demonstrated that the applied pre-treatment was a determining factor in the morphology and particle size of the resulting CNCs.
