抄録	In this paper, β-Si_[6-z]AlzOzN_[8-z] (z = 1) powder was synthesized via combustion synthesis (CS) assisted with mechanical activation by a high energy planetary ball milling under various nitrogen pressures (0.7, 1.0, 1.5, and 2.5 MPa). The effect of ball milling time and nitrogen pressure on the reaction rate and microstructure of CSed products were investigated using XRD and SEM. The effect on the nitrogen pressure required for CS of β-SiAlON was also examined. The results show that prolonged milling time was effective for enhancing the reactivity of raw materials and also for promoting the conversion rate of β-SiAlON. The mechanical activation also minimized nitrogen pressure required for the CS of β-SiAlON, which the reaction can self-propagate at only 0.7 MPa in nitrogen pressure. Significantly, the rod-like crystals agglomerated together with increasing ball milling time, and became longer and thicker with increasing nitrogen pressure.
