| Abstract: | Fine sialon powders (Si6-zAlzOzN8-z, Z = 0.3, 0.6) were prepared by nitriding combustion. Silicon powders was reacted with AlN and Si3N4 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. |
