Abstract

The reaction processes of β-SiAlON(Z=3) powder using carbothermal reduction and nitridation, were investigated on basis of thermo-gravimetry, CO concentration and XRD analysis. The processes were influenced by the reactivity of Al compounds in raw materials. β-SiAlON was synthesized via mullite using high reactive Al compound (AMD or Al(OH)3), on the other hand, synthesized via α-A12O3 using low reactive Al compound (Al2O3).
