Cyclic Compaction of Ceramic Powders

Cyclic compaction is shown to be more efficient than single‐stroke and static compaction. The application of a bias pressure during cyclic compaction decreases the degree of powder compaction. A densification equation, based on the Cooper and Eaton compaction equation, is proposed to describe the cycle‐dependent pressure–volume fraction relation for ceramic powder compaction. Data from cyclic compaction of alumina powder are well represented by the proposed equation.
