Abstract :
SiCf/SiC composites are considered as one of promising candidate blanket structural materials and functional materials for the flow channel insert of LiPb blanket for fusion reactors. One of key issues for the SiCf/SiC composites is its compatibility with LiPb. A variety of SiC materials prepared by different processes (i.e. CVD-SiC, PIP-SiC), coated SiCf/SiC composite (the coating containing Al2O3 and SiO2) and SiO2 were exposed in the static liquid LiPb at 800 °C for 200 h and 1000 h, respectively. The preliminary results showed that PIP-SiC had good compatibility with LiPb at 800 °C. The coating on the SiCf/SiC composite was corroded by liquid LiPb. In addition, the XRD pattern of CVD-SiC integrally moved left a little after 1000 h exposure.
