Spatial tritium transport in single-crystal lithium aluminate

Irradiation effects and hydrogen behavior in H2+ and He+ implanted γ-LiAlO2 single crystals

“…The accumulation of point defects, formation of extended defects and presence of gas species in LiAlO 2 are expected to affect the structural stability, thermomechanical properties, and tritium migration. Previous studies of LiAlO 2 reported in the literature have addressed technical issues of structural defects, volume swelling, micro-cracking, tritium detrapping, diffusion and release using various radiation sources, including x-rays and -rays [4,5], electrons [6,7], neutrons [8][9][10][11][12], and ions [13][14][15]. Modeling of tritium transport [16][17][18] and molecular dynamics (MD) calculations of threshold displacement energies [19], defect production [20,21] and Li diffusion [22] have also been carried out.…”

Toward Understanding the Effect of Water Sorption on Lithium Zirconate (Li2ZrO3) during Its Carbonation Process at Low Temperatures

“…Several lithium ceramics have been widely studied as tritium breeding materials for nuclear fusion reactor, as electronic devices, and in low thermal expansion glass ceramics used in ceramic hobs. [1][2][3][4][5] Additionally, in recent years, these ceramics have been proposed as promising carbon dioxide (CO 2 ) captors as well. [6][7][8][9][10][11] In all these technological applications, as in others, the exposition of lithium ceramics to water vapor may affect its performance.…”

Ceramic breeder materials: Status and needs

“…However, tritium diffusivity was obsetved [53,54] to follow a simple Arrhenius-type temperature dependence, with the diffusivity determined for the doped and undoped materials being the same within experimental error. This suggests that impurities which create lithium vacancies have little or no effect on tritium diffusion investigated.…”
