AGGREGATE STRUCTURE OF FINE POWDER AND COMPACTION PROCESS

摘要

Compacting process of fine powder is greatlyaffected by the aggregate structure of particles.Accordingto the experiment in which several kinds of silicon nitrides indifferent partical shape and size were compacted in uniaxualorientation,it is found that the volume compacting rate offorming body differs with the pressure.The aggregatestructure of each sample A,B or C was estimated byapplying Cooper’s equation to the analysis of the compactingprocess of each
