Sialons, acronym for silicon-aluminum-oxygen-nitride, are refractory ceramics based on silicon, aluminum, nitrogen and oxygen (oxynitrides of silicon and aluminum).
The proportions of oxides may vary. The sialon which has the formula Si3Al3O3N5 consists of a solid solution of alumina (Al2O3) in silicon nitride (SI3N). It is used in particular as a binder of silicon carbide (SiC) in refractory bricks of blast furnace tank. change the code
