Packing Characteristics of Ultrafine Particle Powder

Abstract

It became clear in the present study that the structure of an aggregate of ultrafine particles was strongly affected by (a) a cohesional strength among primary particles and (b) an interaction between aggregates, both of which depends on the synthesizing method of powders and a kind of raw materials used.
Difference in behavior of compaction among those ultrafine powder beds during uniaxial pressing was discussed on the basis of experimental results considering a large difference in elastic strain energy accumulated in the compact beds.
