Boron-doped graphite is one of candidate materials for oxidation-resistant graphite. It was reported that BO, which was generated by oxidation of BC, prevented boron-doped graphite from oxidation. However, to apply boron-doped graphite to core support graphite structure of HTGR, it is necessary to measure the mechanical and thermal property of oxidized boron-doped graphite. This study reports results of oxidation test, bending strength test and surface observation using GB-210 fabricated by Toyo Tanso Co., Ltd. in order to measure the bending strength of oxidized boron-doped graphite.
