In this study, Ti 2 AlC/Ti 2 AlN powders were first incorporated to fabricate low‐carbon MgO‐C refractories, and their oxidation behaviors were investigated. Computed tomography (CT) results indicated that stress cracks only occurred in the Ti 2 AlC‐added sample after exposure to 1100°C, and the anomalous oxidation behavior of Ti 2 AlC powder at 578°C worsened the oxidation result at 1100°C for MgO‐C refractories with Ti 2 AlC. At 1500°C, the oxidation behaviors of MgO‐Ti 2 AlC/Ti 2 AlN‐C samples revealed a slight mass gain due to the disintegration of Ti 2 AlC/Ti 2 AlN, and their oxidation resistances increased by 18% as compared to their counterparts. In addition, the role of Ti 2 AlC/Ti 2 AlN was elucidated. The oxidation process was comprehensive and was mainly determined by the deterioration of carbon and MAX phases. The obtained results indicated that Ti 2 AlN was more suitable for fabricating low‐carbon MgO‐C refractories as compared with Ti 2 AlC.
