Abstract
In recent years, “high temperature” ceramics as materials with 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 materials for high temperature incinerator. High-temperature oxidation behavior of sintered SiB6 body was studied in air at 573-1273K for 5min to 25h by measuring mass gain and X-ray diffraction. In spite of increasing temperature and time, weight gain by oxidation of sintered SiB6 body was not approved at 1273K. However, the oxidation was confirmed by X-ray diffraction analysis at higher then 873K.
