The Synthesis of Submicron β-SiC Powders and the sintering behaviour have been studied. With the raw meterial of Si02and C powders as the main material, the particle size of SiC powders possessed less than 0.5μm is obtained. And through the observation of the relations among the sintering density, flexure strength and the maintenance time under certain temperatures and pressures as given, the hot-pressing technique suitable for β-SiC has been determined. The resulted sintering material has a relative density of 99% and flexure strength of 600 MN/m2.
