After introducing topics in each fabrication process, the state-of-the-art of mechanical properties of SiC, Si
3 N
4 and sialon are illustrated. Fabrication in a clean environment could make variance of such properties decreased. For first wall material, SiC and TiC are picked up. SiC has been widely studied and has a supreme irradiation resistance. TiC shows rather metallic behavior in mechanical property and thermal conductivity, which may give advantages for the first wall, although there are few irradiation data on TiC. For electric insulator, BeO, Al
2O
3, MgAl
2O

3N
4, AlN and AlON can be the candidates.
