Addition of nanocarbon black up to 3 wt% was done in M g O ‐ C refractories, containing fixed 3 and 5 wt% of graphite, to study the effect on various refractory properties. Uniform distribution of carbon particles even at 1 wt% of nanocarbon black with 3 and 5 wt% of graphite was found to improve the refractory properties. The coked strength, hot strength, corrosion resistance, and oxidation resistance were found to be improved for nanocarbon‐containing M g O ‐ C refractory compared with the conventional refractory due to in situ formation of A l 4 C 3 . Higher amount of nanocarbon black was found to deteriorate the refractory properties.
