Compaction process of granules was studied by compressing a granule bed with a constant rate increase of applied stress. Compaction process at the lower range of applied stress proceeded with the decrease of intergranular void volume. The change of the intergranular porosity, εi was expressed as In (εio/εi) = (P/Pc) In (εio/εif) in the stress range from 0 to Pc, where P is applied stress, εiois the initial intergranular porosity and εif is the intergranular porosity at Pc •Pc was nearly proportional to the granule strength, pgand expressed by(l-εif)ρg.
