Abstract
The morphological changes of particles through three different processes (impaction, compaction and grinding) were investigated experimentally. This was done using two types of antimony trioxide (Sb2O3)-fine particles which have almost the same particle size distributions but different surface properties. One has the sulfate group (-SO4) on the surface; the other does not.<br>It is found that the diameter of the Sb2O3 particles having -SO4 begins to increase at lower impaction velocity or at lower compaction pressure than those having no -SO4 does. Estimation of the load applied on a single particle through these two processes reveals that the threshold of the load inducing the particle enlargement is almost the same for impaction and compaction.<br>The tendency for the diameter to change through grinding is opposite to that through impaction or compaction. However, the Sb2O3 particles having -SO4 keep higher crystallinity than those having no -SO4 among these three processes.
