Five lightweight castables containing different Ti O2 additions were prepared by using porous corundum-spinel( Mg Al2 O4) ceramics as aggregate. Corrosion of the lightweight castables by ladle slag was conducted using a static crucible test. The effect of the Ti O2 addition on the slag resistances of the lightweight corundum-spinel castables was investigated through SEM,EDS and FactSage¡Lsoftware,etc. It was found that Ti O2 additive promoted the sintering degree of the castables,decreased the average pore size,the apparent porosity,and the contact area between the castables and slag,and then enhanced the corrosion resistance. However,Ti O2 additive decreased the viscosity of the penetrated slag simultaneously,and then deteriorated the penetration resistance.
