A novel approach was developed for synthesizing sialon in an air atmosphere, and then used to obtain O′-sialon bonded corundum composite ceramics (O′-sccc) by a sintering reaction process in an air atmosphere. The morphology, microstructure, and properties of the O′-sccc were investigated. The process of forming sialon by air atmosphere sintering is discussed. It was found that a novel configuration, using fused white alumina, alumina powder, and ferro silicon nitride powder, allowed the synthesis of sialon without a controlled nitrogen atmosphere furnace.
