The size distribution of Cpt is remarkably narrowed by using vibro‐ and wet ball milling. The crystallinity of Cpt noticeably decreases for the samples obtained by ball milling while vibro‐ and ultrasonic millings show a negligible effect on crystallinity. The specific surface area of Cpt is enhanced by all four milling methods.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
