Stability of SiC/SiC fibre composites exposed to Li4SiO4 and Li2TiO3 in fusion relevant conditions
Source abstract
Abstract
Abstract The physico-chemical stability of a commercial 3D SiC f /SiC composite provided with an outer CVD SiC protective layer was studied after exposure to flowing helium with 0.1% H 2 at 800°C in contact with lithium silicate and lithium titanate. Exposure tests were carried out for 216, 1000 and 10 000 h in an especially designed loop. The mechanical characteristics of the SiC f /SiC composite in contact with Li 4 SiO 4 were almost unaffected by the exposure, while those in contact with Li 2 TiO 3 were slightly worsened. SiC coating transformation was clearly detected on samples exposed to both lithium silicate and titanate.
