Development and Application of the Mullite Bricks with Low Creep for Anode Baking Furnace

Shandong Refractory Co.,Ltd. developed low creep mullite bricks with low high temperature creep rate,high load softening point and excellent thermal shock stability. The products used the mullite as aggregate adding corundum powder and silica powder. The aggregate formed the skeleton of the mullite after sintering at high temperature. The mullitization of the added the corundum powder and silica powder formed mullite mineral phase,which fills in the mullite skeleton and enhances the products of high temperature creep property.
