| Abstract: | As a result of addition of fine zircon powder, change of some properties of high purity andalusite based refractory,such as sintering property,thermal shock resistance and creep resistance, were investigated. The experimental results show that adding proper amount of zircon powder to high purity andalusite based refractory can improve sintering state and thermal shock resistance of the material, but it is disadvantageous to creep resistance of the material.In addition,the mechanism of zircon improving thermal shock resistance and microstructure of the material were analysed by XRD and SEM. |
