Abstract
Particular features of the compaction of dielectromagnetic materials and factors affecting the attainment of required density are described and discussed. The dependence of density on compaction pressure is shown to Qe approximated by an exponential curve. Models are presented illustrating the effects of compaction on magnetodielectrics with various dielectric/pore volume ratios, as well as of changes in particle shape, cold work, and internal stresses. The possibility of improving magnetic properties of dielectromagnetics by recrystallisation annealing is considered. PM/0466
