Abstract:

Silicon powder and aluminum powder are added into the matrix of corundum based refractory, β-Sialon is formed through in-situ nitrogenizing reaction and it is used to prepare β-Sialon bonded composite phase material. The effect of β-Sialon formed amount on the physical property, mechanical property, thermal shock resistance and so on of the material is studied. The phase composition and microstructure of the material are analyzed by XRD and SEM.
