Silicon nitride and sialon ceramics
Current Opinion in Solid State and Materials Science, 1999The most intriguing recent development in the field of silicon nitride ceramics has undoubtedly been the discovery of a cubic form of silicon nitride. Major advances were made in α-SiAlON ceramics, including the development of thermally stable, in situ reinforced grades.

Processing of silicon nitride ceramics
Materials Science and Engineering: A, 1989Abstract The conventional powder metallurgical route for the manufacture of silicon nitride ceramics involves powder preparation, mixing, shaping and sintering or hot-pressing at temperatures typically above 1700°C. The oxygen distribution in the nitride powders strongly influences the stability and rheology of suspensions for colloidal powder ...

Silicon Nitride and Sialon Ceramics—A Review
Canadian Metallurgical Quarterly, 1988AbstractSilicon nitride and sialon ceramics are receiving a great deal of attention as potential high temperature structural materials for engines and other demanding applications. The sintering behaviour and high temperature preformance of these ceramics is strongly influenced by the sintering additives, impurities and powder characteristics of the ...

Perhydropolysilazane precursors to silicon nitride ceramics
Journal of Inorganic and Organometallic Polymers, 1992Preceramic perhydropolysilazane has been synthesized by the ammonolysis of dichlorosilane pyridine adduct. Perhydropolysilazane was polymerized and cross-linked by heat treatment with or without ammonia by dehydrogen condensation between SiH and NH and disproportionation at the SiH site in the polymers in the presence of pyridine.
