In recent years, high temperature ceramics as materials with high strength and high melting point are drawing the attention for ceramists. These ceramic materials are expected to be used as a fireplace for nuclear fusion, aircraft engine, rocket nozzle and fireplace material for high temperature incinerator. High-temperature oxidation behavior of sintered Cr3C2 body was studied in air at 300-1400°C for 5min to 25h by measuring mass gain and X-ray diffraction. In spite of increasing temperature and time, weight gain by the oxidation of sintered Cr3C2 body was not approved at 1400°C. However, the oxidation was admitted by X-ray diffraction analysis at higher then 600°C.
