“…The most acceptable and effective approach is the usage of antioxidant in the form of metal powders, alloys, carbides, borides, and even oxides 7,8,9,18–23 . Ternary carbides have outstanding properties for high‐temperature applications, such as low density, high strength, low thermal expansion coefficient, high resistance to thermal shock, good thermal conductivity, and hydration resistance 24–31 . Considerable research efforts have been performed to develop alternative antioxidants with optimized properties and less drawbacks, and the exploration and application of single ternary carbide, such as Al 4 O 4 C, “Al 8 B 4 C 7 ,” Al 4 SiC 4 , Ti 3 AlC 2 , and Ti 3 SiC 2 , have been proved to have benefits 25,27,29–31 .…”
