Pulverization and Dispersion Technique for Agglomerated Particles of Alumina Powder in a Slurry

Abstract

A technique was developed to pulverize agglomerates in a slurry into primary particles. Pulverization increased the powder packing density of alumina green sheets from 50 to 61 vol%. The sinterability of alumina was also increased. The internal voids in the sintered body were drastically reduced.
