Compacting characteristic of fine particles is greatly affected by the aggregate structure of particles. Several kinds of silicon nitrides,which are different each other in particle shape,size and bulk density,were compacted in uniaxial direction under various conditions,and the behavior of the particles during compaction was analyzed and compared by using Cooper's equation. As a result it was found that the difference in the kind of samples and the condition of their pretreatment gave considerably different behavior during compaction, and that the apparent volume reduction rate under pressure was remarkably different at low and high pressures. The aggregate structure of each sample was estimated based on the above results together with the result of the measurement about the compaction structure of the molded bodies.
