The physico-chemical stability of SiC/SiC fiber ceramic composite (SiC/SiCf) in contact with Li2O in fusion-relevant conditions has been experimentally studied at 800°C in flowing helium (0.1 L/min) containing either 0.1% H2 or 100 ppm H2O and for exposure times of up to 4032 h. The exposed SiC/SiC specimens have been characterized. The results obtained demonstrate that although the surface coating of the specimens is strongly attacked through chemical corrosion processes, the main physico-chemical characteristics of SiC/SiCf are affected to a limited extent only in the case of He+0.1% H2 flowing gas, the bulk material not being attacked.
