Abstract
We studied the densification and phase formation processes during reactive sintering of the β-sialon charges based on the β-modification of silicon nitride with an insignificant weight content of aluminum. Densification of the charge occurs according to the regularities of the liquid phase sintering process during which the liquid phase disappears. The kinetics of densification and phase formation and the degree of completion of these processes depend on the composition of the original charge and the degree of dispersion of the powders of the additives. Under the present sintering conditions, the process of β-sialon formation from β-Si3N4 occurs according to the mechanism of dissolution and redeposition through a liquid phase with a significant contribution from the processes of mass transport through a gaseous phase.
