| Abstract: | The mullitization of andalusite from Xinjiang,Chi-na and influence of aggregates on properties of alumino-silicate refractories were studied by XRD,SEM,EDS,DSC.It was found that mullitization was obvious at 1 400 ℃.but considerable at 1 500 ℃.The refracto-ries with corundum aggregates had the highest RUL and the lowest creep rate,but refractories with bauxite aggre-gates had the lowest RUL and the highest creep rate. |
