The effect of precursor composition and sintering additives on the formation of ß-sialon from Al, Si and Al2O3 powders [PDF]
A study was performed to investigate the effect of increasing the Al or Al2O3 precursor content, above the stoichiometric amount, on the formation of β-sialon by pressureless sintering of Al, Si and Al2O3 powders in flowing nitrogen gas.
