摘要：
The addition of C/MgAl2O4 composite powders can improve the thermal shock resistance of low-carbon Al2O3-C refractories attribute to the formation of microcracks in the agglomerated structure, thus consuming more thermal stress and strain energy. Moreover, C/MgAl2O4 composite powders additive promote the formation of short fibrous ceramic phases in the refractories, which suggest a bridging role in the interior of the refractories and increase its toughness. Furthermore, the C/MgAl2O4 composite powders also result in a remarkable enhancement of the slag corrosion resistance in the refractories.
