- ABSTRACT: Alumina-magnesia refractory castables have been widely used in the wall and bottom impact pad of steel ladles. The properties of alumina-magnesia refractory castables with SnO<sub>2</sub> additive in 0 - 5 wt% range were investigated. The phase composition, microstructure, physical and mechanical properties of these refractories were studied. The results showed that the addition of SnO<sub>2</sub> could have a great influence on the properties of alumina-magnesia refractory castables. The expansion, apparent porosity and strength of refractories with SnO<sub>2</sub> were all more prominent than those of reference samples, which were attributed to the formation of CA<sub>6</sub> and enhanced bonding. Meanwhile SnO<sub>2</sub> could react with spinel and CA<sub>6</sub> to form solid solution.
