State-of-the-art of SiAlON materialsThe state of the art of 'SiAlONs' is reviewed, noting that the term has become a generic one applied to Si3N4 based materials. Attention is given to work on phase relations, crystal structure, synthesis, fabrication, and properties of various SiAlONs. Also discussed are the essential features of compositions, fabrication methods, and microstructures. In addition, consideration is given to high temperature flexure strength, creep, fracture toughness, oxidation, and thermal shock resistance. Finally, these data are compared to those for some currently produced silicon nitride ceramics to assess the potential of SiAlON materials for use in advanced gas turbine engines.
