Description
Li-Zr-Si mixed oxides were irradiated in a mixed radiation field in order to produce tritium through the Li6(n, α)H3 reaction. The LiZrSiO4 samples, prepared with different Li:Zr molar ratios (1, 3, 5 and 6), presented high tritium diffusion compared with other lithium ceramics like Li2SiO3 and Li2ZrO3. Furthermore, their composition and structure were not modified after irradiation. It was also found that Li2ZrSi6O15 was damaged by irradiation, and that tritium release was moderate in this compound. (authors)
