The calculations show that the strip effect energy work on silica white particles from mill balls is 1·78 × 10 –9 J. This number is greater than the effect energy needed in disaggregation which is calculated to be 2·33 × 10 −10 J. The stripping of grinding ball could be an important mechanism on the disaggregation of silica white …

We think silica gel is a good grinding auxillary to break π-πstacking in under mechanochemical conditions and it also could serve as catalyst. The rate enhancement effect of silica gel could be a combination of surface charge, small particle size, ability to absorb moisture and acidity of silica gel. However we believe the most important ...
