Analysis of structural parameters for compacted porous materials. I. Compaction by pressing

Convenient expressions are obtained that describe the structural parameters of monodispersed two- and three-dimensional powder systems compacted by pr essing. The procedure is based on a structural model for monodispersed powd er materials and an approximation by which with a reduction in porosity Vor onoi polyhedra are assumed to be unchanged but the volume of pores decrease s as a result of a corresponding increase in particle diameter This makes i t possible to obtain good agreement with experimental results over a wide r ange of change in porosity.
