Abstract

The aggregation, separation, and agglomeration behaviors of MgAl2O4 inclusions were observed by CLSM. From these observations, it was found that the cavity bridge force between two inclusion particles plays a dominant role in the process of agglomeration, and that the action distance of the cavity bridge force is proportional to the radius of the MgAl2O4 inclusion. Once a stable cavity bridge between two MgAl2O4 particles forms, the aggregated MgAl2O4 inclusion cannot be separated again.
