Effect of B4 C on Oxidation Resistance of Low-Carbon MgO-C Materials

B4C was added into the low-carbon MgO-C materials in order to improve the oxidation resistance. The results show adding 0. 3wt% B4 C can get the best oxidation resistance and adding 0.2wt% B4C can get the highest hot modulus of rupture. Altogether, adding 0.2wt% B4C into the low-carbon MgO-C materials can get better oxidation resistance and hot strength.
