Conditions for Observing Densification Process in Pure Form,ing 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

Volume of Pores in Relation to Isothermal Sintering Time,s with time of the parameters characterizing the development of the process. Although measuring the reduction of linear dimensions or the volume of a sintered body with time presents no experimental difficulties, the investigation of the kinetics of densification of powders is far from complete.

Change in the Surface and Volume of Pores under Various Sintering Conditions,in crystals — that are primarily responsible for the course of densification. During sintering there are signs of the development of still another elementary process — migration of the substance along the surface of pores (self-diffusion surface). The outward manifestation of this process is a subst

Phenomenology of Sintering and Modern Theoretical Concepts,ndent processes, after which one can attempt to establish (quantitatively) their interdependence and their effect on densification. The problem would be completely solved if it were possible to describe these processes on the basis of modern physical concepts of lattice imperfections and their part

Quantitative Estimate of the Effect of the Substructural Factor,s of comparing the general densification law expressed by Eq. (III-14), reflecting the combined effect of the geometric and substructural factors on the densification process, with Eq. (IX-4), characterizing the effect of the geometric factor alonC. This method made it possible to propose a mathemat
