Abstract

Compaction processes of α-Fe₂O₃granules have been studied through changes of intra and intergranular pore volume measured by mercury porosimetry. Densification of compacts mainly occurred by the elimination of inter-granular pores due to the plastic deformation of granules. Intra-granular pores remained unchanged during the compaction process under the stresses below 1000 kg/cm². Amount of inter-granular pore increased with the increase of the binder concentration but was not dependent on the yield strength of granules.
