SiB4 has excellent chemical property as well as low thermal conductivity and high electric conductivity at high temperature, so it is promising as a thermoelectric material. SiB4 was made by hot-pressing. The oxidation behavior of SiB4 sintered body was studied in air for 5min to 25h ranging at 773 to 1373K by mass gain and XRD. The SiB4 was slightly oxidized up to 1173K. However, mass gain of the SiB4 increased markedly at 1273K.
