Obtaining of Nanocomposites in SiC-SiAlON and Al2O3-SiAlON System by Alumothermal Processes


Composites were obtained in the in SiC-SiAlON and Al2O3-SiAlON system. Physical-chemical processes going on at the obtaining of SiALON within the range of 800°C - 1500°C were studied. Charge compositions and sintering regime were selected. It was proved that X-SiALON was obtained at the sintering of kaolin-aluminum powder at 1500°C, while β-SiALON was formed at the sintering of SiC-Aluminum powder, silicium and Al2O3-aluminum powder, silicium at 1500°C. Corrosion properties of the materials were studied. Investigations were performed by the methods of X-Ray structural and microscopical analysis.
