Preparation and High Temperature Performance of β-Sialon Bonded Corundum Multiphase Material

Abstract:

Article Preview

β-Sialon bonded corundum multiphase ceramic refractory was prepared by the method of carbothermal reduction and nitridation reactions of clay mineral doped with corundum particle phase. The high-temperature oxidation resistance and the thermal-shock resistance behaviors of the material were tested and investigated. The results show that the oxidation reaction history at 1573K can be divided into two reaction kinetic phases. The circle times of the thermal-shock resistance ($=1473K) reached to more than 200 times and the thermal shock failure is not a brittle rupture but a desquamate damage.
