The corrosion measurements with percentage, the penetration depth of molten steel and the microstructure of the refractories were evaluated after soaking 150 h at the temperature of 1500˚C. Results showed that the corrosion resistance of alumina increased by adding 20 wt% zircon, and decreased with further increasing of zircon. Also, the samples containing 20 wt% of zircon obtained the minimum porosity. Microstructural features of this composite showed needle-like mullite grains and higher amount of zirconia particles which may be responsible for providing the corrosion resistance to melt penetration.
