Effects of ball milling time on microstructure evolution

2014-8-1  The ball milling time, which determines the particle size, is closely related to the final density due to the sensitivity of different diffusion processes to particle size. As described in Ref. [41],neck growth between contacting particles is very common in sintering process and equations of the neck growth for each transport mechanism usually depend on the particle size.

Ball Milling an overview ScienceDirect Topics

Ball milling and ultrasonication were used to reduce the particle size and distribution. During ball milling the weight (grams) ratio of balls-to-clay particles was 100:2.5 and the milling operation was run for 24 hours. The effect of different types of balls on particle size reduction and narrowing particle size distribution was studied.
