Influence of Adding Corundum Powder to Kiln Refractory
Influence of Adding Corundum Powder to Alumina-Magnesia Refractory Castable.

Thermal shock resistance properties of refractory
· This results in high resistance to crack propagation. In other words the microcracks are caused by the thermal expansion mismatch between the corundum and spinel creating a toughening effect which improves the thermal shock resistance of the refractory castable. As a result and as seen in Fig. 12(b) many radial cracks exist in the MC32
