Conditions for Observing Densification Process in Pure Form
In plots of vs/vp vs. dp one observes both random and systematic deviations from constant values of vs/vp. The first may be due to nonidentical sintering conditions of bodies with different initial porosities and other accidental circumstances. Systematic deviations that are consistently observed in sintering of bodies from a given powder are usually closely connected with the structural characteristics. In most cases the reason for the deviation from a constant value of the specific reduction in volume of pores can be determined.
