摘要：

The Al 2 O 3 - ZrO 2 - C material was prepared using tabular alumina aggregates and fines, zirconia-corundum, zirconia-mullite, flake graphite, B 4 C powder, Si powder and different nano-oxides (nano-ZrO 2 , nano-TiO 2 , and nano-Al 2 O 3 ) as raw materials, the effects of different nano-oxides on the corrosion resistance and microstructure evolution of Al 2 O 3 - ZrO 2 - C material were investigated. The results showed that the high reactivity nano-ZrO 2 , nano-TiO 2 , and nano-Al 2 O 3 particles reacted with CaO to generate high melting point phases of CaZrO 3 , CaTiO 3 , CaO center dot 6Al 2 O 3 (CA 6 ) at high temperature, which forms a protective layer at the interface between corroded media and samples, inhibiting CaO penetration into the material. Additionally, nano-oxides can fill the pores and increase the density of material, thereby contributing to improving the penetration resistance and corrosion resistance of material.
