Abstract
The electric conductivity and shrinkage of pieces molded from corundum powders of different dispersion were simultaneously measured to investigate diffusion processes in solid-phase sintering. The mechanism of the successive effects observed was considered: desorption of adsorbed atoms, diffusion in near-surface regions of the particles, bulk diffusion. The possibility of controlling of sintering in controlled conditions of temperature elevation was demonstrated.
