“…Lithium aluminate, LiAlO 2 , is a potential candidate material for the tritium breeder of a fusion reactor or the electrolyte matrix of a molten carbonate fuel cell (MCFC) due to its chemical and thermal stability as well as low radiation damage susceptibility. The capture of a neutron by 6 Li is known to occur as follows: In preparing ceramic materials, it is important to be able to have precise control over the microstructure, since the microstructure is considered to play an important role in controlling tritium release kinetics from the blanket .…”

Lithium aluminate nanorods were successfully synthesized from Al2O3 nanoparticles and lithium hydroxide by a simple, large-scale hydrothermal process without any surfactant or template. The various reaction parameters were optimized to achieve the maximum yield. The as-obtained nanorods had orthorhombic beta-lithium aluminate structure with edges in the range of 40-200 nm and lengths of 1-2 mum confirmed by SEM, TEM, XRD, and NMR. Upon calcination at 1273 K for 12 h it transformed to gamma-lithium aluminate, yet maintained the initial morphology, demonstrating the thermal stability. The ratio of lithium hydroxide to aluminum oxide showed a significant effect on the morphology as Li/Al = 1 gives "microroses", whereas Li/Al = 3 and Li/Al = 15 gave "microbricks" and "nanorods", respectively. Investigation of the mechanism showed that the nanorods were formed via a "rolling-up" mechanism. As we used all-inorganic raw materials and a simple synthetic procedure under mild conditions, the scale-up of this process for large-scale production should be very easy.
