Abstract
Special features of formation of the microstructure and phase composition of sintered materials based on Si3N4 and α-sialons synthesized in the Si - Y - Al - O - N system by the method of compressive and microwave sintering are described. It is concluded that the morphology of the initial Si3N4 powders, the phase composition of the initial mixture, and the sintering technology of the ceramics in the decisive stage determine its microstructure, including the processes of self-reinforcement by β-Si3N4 crystals, the phase composition, and the physicomechanical characteristics.
