Carbon nanotubes (CNTs) have been extensively studied over the last two decades since they possess excellent properties. CNTs have been considered as new promising reinforcements for carbon containing refractories (CCRs). Current research progress of the CNT-reinforced MgO-C and Al₂O₃-C refractories was summarized in this mini-review, and the CNT-reinforced CCRs possess remarkable mechanical properties and superior thermal shock resistance compared to CCRs without CNTs.
