Reaction sintering of silicon oxynitride.
Journal of the Japan Society of Powder and Powder Metallurgy, 1989 Silicon oxynitride (Si2N2O) ceramics were fabricated from equi-molar mixtures of Si3N4 and SiO2 with 5 wt % Al2O3 as a sintering aid by heating at 1650-1950°C for 1 h in 980 KPa N2. The initial stage of densification was due to the solution and repreci-pitation of Si3N4 through a liquid phase of SiO2-Al2O3 system.
