Fine sialon powders (Si 6‐z Al z O z N 8‐z , Z = 0.3, 0.6) were prepared by nitriding combustion. Silicon powders was reacted with AlN and Si 3 N 4 under 10 MPa of nitrogen gas. The reaction temperature reached above 2000°C and single‐phase sialon powders were synthesized within minutes. The obtained powders were fully densified without additives by hot isostatic pressing. The sintered body had a flexural strength of 600 MPa by 4‐point bending.
