Abstract

The possible participation of excess vacancy generation and annihilation processes in the formation of “active imperfections,” and the effect of these processes on the kinetics of pore volume shrinkage are considered. The proposed three-stage model x-U-y-W includes a system of equations from which the W(t, T) relationship for isothermal and nonisothermal sintering regimes can be calculated with the aid of a computer (W=v/v, where v=pore volume).
