The Aggregate Structure of Fine Particles and Compacting Process [Translated]†
The compacting characteristic of fine particles is greatly affected by the aggregate structure of particles. Several kinds of silicon nitrides, which are different from each other in particle shape, size and bulk density, were compacted in a uniaxial direction under various conditions, and the behavior of the particles during compaction was analyzed and compared by using Cooper's equation. It was found that the difference in the kind of samples and the condition of their pretreatment resulted in considerably different behaviors 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 of the compaction structure of the molded bodies.† This report was originally printed in Journal of the Society of Materials Science, Japan, 35(398), 1246-1250 (1986) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc. of Materials Science, Japan.
