| Abstract: | Addition of nanocarbon black up to 3 wt% was done in MgO‐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 MgO‐C refractory compared with the conventional refractory due to in situ formation of Al4C3. Higher amount of nanocarbon black was found to deteriorate the refractory properties. |
