Laws Governing the Relationship between the Initial and Final Densities of Sintered Bodies

A review of the laws governing densification during sintering should begin with the constant specific reduction in the volume of pores, which was established twenty years ago [1]. When porous bodies compacted from a given powder at different pressures, and differing in initial porosity, are sintered under the same conditions, the volume of pores is the same in all bodies in most cases. If Vp and Vs are the volumes of pores before and after sintering, then Vg/Vp = const (on condition that densification is not disturbed by associated processes that affect the volume of the sintered body).
