“…The lack of objective data on the processes of corrosion and degradation in corrosive media opens up broad prospects for researchers to conduct such experiments. Interest in them is due to the possibility of obtaining kinetic curves of the degradation rate, which in the future will make it possible to contribute to the characterization of lithium-containing ceramics for thermonuclear power engineering [21][22][23][24][25]. Also of particular interest is the study of the effect of the presence of two-phase structures on resistance to degradation, since earlier studies indicate that two-phase ceramics have higher strength and durability [25][26][27].…”

The interest in lithium-containing ceramics is due to their huge potential as blanket materials for thermonuclear reactors for the accumulation of tritium. However, an important factor in their use is the preservation of the stability of their strength and structural properties when under the influence of external factors that determine the time frame of their operation. This paper presents the results of a study that investigated the influence of the LiTiO2 phase on the increasing resistance to degradation and corrosion of Li2TiO3 ceramic when exposed to aggressive acidic media. Using the X-ray diffraction method, it was found that an increase in the concentration of LiClO4·3H2O during synthesis leads to the formation of a cubic LiTiO2 phase in the structure as a result of thermal sintering of the samples. During corrosion tests, it was found that the presence of the LiTiO2 phase leads to a decrease in the degradation rate in acidic media by 20–70%, depending on the concentration of the phase. At the same time, and in contrast to the samples of Li2TiO3 ceramics, for which the mechanisms of degradation during a long stay in aggressive media are accompanied by large mass losses, for the samples containing the LiTiO2 phase, the main degradation mechanism is pitting corrosion with the formation of pitting inclusions.

“…Materials science studies conducted as part of the implementation of international programs for the creation of fusion reactors ITER and DEMO have shown that one of the best materials for use as an PFM (plasma-facing material) [1] in controlled fusion plants is liquid lithium and materials based on it [2,3,4]. The use of liquid lithium as a plasma-facing material is especially promising if lithium is enclosed in a so-called capillary-porous system (CPS) [5,6].Currently, there are many studies in the world conducted with lithium CPS, which once again confirms the interest in this material [7,8,9,10,11,12,13].Work on this topic is also being carried out at the Kazakhstan Materials Science Tokamak KTM [14,15,16,17,18,19,20]. The installation is currently the only tokamak in the world designed to solve problems in the field of thermonuclear materials science.…”

This work is devoted to testing a lithium CPS based on carbon fabric reinforced with carbon nanotubes under conditions of thermal and radiation loads. The paper considers and analyzes: the properties of carbon nanotubes and methods of their synthesis, the nature of the interaction of carbon materials with liquid lithium at different temperatures. A description of all the main stages in the manufacture of lithium CPS based on carbon fabric reinforced with carbon nanotubes is given. Microstructural studies of a manufactured lithium CPS sample based on carbon fabric reinforced with carbon nanotubes are presented. Studies have shown that a carbon fabric with a fiber surface reinforced with carbon nanotubes is completely wetted by liquid lithium. The developed technology is fully suitable for the manufacture of lithium CPS samples for further research. The results of experiments on the interaction of lithium CPS based on graphite fabric reinforced with carbon nanotubes with hydrogen isotopes under thermal and radiation loads are presented.
