Evaluation of silicon doped CFCs for plasma facing materialFunded under: EAEC-FUSION 12C
To improve the CFCs' characteristics of chemical erosion, tritium retention, and H(2)O/air resistivity, silicon doped CFCs were developed by the European Fusion Technology project. The tritium retention, H(2)O reaction kinetics, outgassing behaviour and depletion of silicon in doped CFCs were investigated as a function of silicon concentration and temperature. The results show that silicon in bulk of CFCs decreases the tritium bulk retention and the H(2)O reactivity. However, it has been observed that the concentration of silicon is slightly decreased at elevated temperature. This paper presents the experimental results, and discusses the behaviour of silicon doped CFCs.
