Physical chemistry of sintering. Textbook

The modern concepts of the physicochemistry of high-temperature densification and strengthening (sintering) of objects of various nature, both metallic and refractory non-metallic, are presented. The processes occurring at the individual contact of mutually sintering particles, with a decrease in volume of both isolated pores and pore ensembles, are considered. The role of structural defects in the crystalline lattice - vacancies, dislocations, grain boundaries in the sintering process of porous bodies is analyzed. The peculiarities of the sintering process of mixtures of powders of different substances in connection with the possible influence of mutual diffusion on the process kinetics are discussed. The regularities of sintering materials involving a liquid phase of various nature are presented.
