- Sputtering can be broadly classified into physical sputtering, chemical sputtering, and sublimation enhanced sputtering. By reducing the sputtering rate by lowering the surface temperature, it is possible to suppress the consumption of the graphite member due to ion irradiation. It is considered that the surface temperature can be lowered by increasing the thermal diffusivity and specific heat of the carbon substrate. Since the thermal conductivity is the product of the thermal diffusivity and the specific heat, even if the thermal conductivity is high, if the thermal diffusion and specific heat are below the threshold value, the result may be poor. An example is given. An electrode material can be considered as a material having high thermal conductivity but low specific heat.
- the electrode material has a bulk density of about 1.6 5 Mg Z cm 3 and a thermal conductivity of 20 O WZ (m- K) is exemplified. In this case, if it is consumed by sputtering, there is a risk that the heat conduction will drop sharply due to a decrease in specific gravity and specific heat.

When carbon reaches a temperature higher than the thermal history due to ion irradiation, gas is released from the inside of the carbon. Is done. This gas becomes submicron carbon particles and is considered to be a source of particles.
- the present inventors thought that prevention of phonon scattering was the most important for increasing heat conduction. It is important to develop materials with high specific gravity while preventing scattering of phonon. In order to increase the free process length of phonon, materials with no interface are required, and it is generally considered to increase the filler. However, in general isotropic graphite, when the particle size of the filler is increased, the specific gravity decreases, and there is a concern that the specific heat may decrease. Therefore, it is conceivable to increase the specific gravity by repeating the pitch impregnation. If repeated pitch impregnation is performed on the fired product, the specific gravity increases, but high thermal conductivity cannot be obtained.
- the present invention incorporates the ideas exemplified below.
- the graphite material after the graphitization is pitch impregnated and further heat treated, for example, heat treated at 2900-3200 ° C to increase the degree of graphitization, and as a result, the thermal conductivity is improved. Give a thermal history for use as a member.

After firing this formed shape at about 100 ° C, pitch impregnation and firing are performed. Repeated several times. Thereafter, graphitization was performed at about 3000 ° C. Then, after impregnating the pitch and firing, it was again graphitized at about 3000 ° C.
