Abstract: Simultaneous sintering of SiC and C was completed with the powder metallurgical method, and with which a near dense
plasma facing material with 0~100% compositional distributions of SiC---bulk SiC/C FGM was obtained. Well graded composition and structure of that composite
were demonstrated by SEM analysis. SiC/C FGM combines the well erosion resistance of SiC and high thermal-shock resistance of graphite, and has the high
effective thermal conductivity and thermal fatigue resistance. Chemical sputtering and Takamok irradiation experiments indicate that SiC/C FGM has
good high temperature plasma erosion resistance.

Key words: FGM, plasma facing material, thermal conductivity
