| 内容： | To provide a material having higher specific rigidity and also denser as compared with silicon carbide, and to provide a method for producing the same. ! The high rigidity ceramic material comprises silicon carbide of 50 to 95 pts.mass, boron carbide of 5 to 50 pts.mass and free carbon of 0.1 to 5 pts.mass, and has a specific rigidity of ≥130 GPa×cm3/g. Upon mixing, aluminum or an aluminum compound is added by 0.1 to 5 pts.wt. expressed in terms of aluminum, and firing is performed in an inert gas atmosphere or in a vacuum, so as to obtain the material. !
