Abstract: This paper summarizes current developments and ongoing research of MgO-C bricks, both at home and abroad, and especially analyzes antioxidant and low-carbon aspects. A future research direction regarding MgO-C bricks was proposed based on the discussion. Specifically, the property improvement of traditional MgO-C bricks through component optimization and structural design, the development of a new antioxidant, improvement of MgO-C bricks in low-carbon methods, and evaluation of corresponding properties, were proposed.
