Study on mechanochemical effect of silica for short

Silica was ground in an oscillating mill at various grinding period to study the mechanochemical effect in fine grinding process. The ground particles exhibited massive size reduction where the volume moment diameter of 5.56 mu m was reached within 600 s. Aggregation of fine particles was very pronounced when it was ground for 600 s due to high surface energy.
