摘　　要：Studies were conducted on how the structure and property of magnesia castable was affected when the magnesia zirconia calcium composite was incorporated. The experimental result indicates that the component CaZrO 3 is easily decomposed by reacting with silica fume to form a low melting point material CMS and CaZr 4O 9 in the silica fume bonded MgO castable, resulting in occurrence of microcracks, which will improve the thermal shock resistance and strength at moderate temperature. In a word, CaZrO 3 improves slag infiltration resistance in spite of lowering the slag corrosion resistance, by absorbing and reacting with components in the slag like Al 2O 3, TiO 2 and FeO.
