Abstract
The properties of ferrite granules are influenced by the characteristics of their precursors; powders and slurries. The properties of granules have a marked effect on the compaction behaviors and microstructures. The plastic viscosity and Bingham yield point of the slurry mixed with dry-milled powders were higher than that with wet-milled powders. The granules produced by dry-milled powders contained large pores, but the granule density was high. The density of the green body produced by dry-milled powders increases at lower compacting pressures. The sintered body produced by dry-milled powders showed lower density because numerous large defects retained.
