This ratio is about 4.6 times higher for the silica aggregates precipitated in the presence of grinding media (about 2.6) compared to the silica aggregates precipitated at standard conditions (about 0.56). Moreover, the residual deformation is about three times higher for the aggregates precipitated under the use of grinding media.
