“…27 Figure 9 shows the crushing load and relative density of ceramic pebbles at different sintering temperatures. The relative density of ceramic microspheres can be calculated via actual density divided by theoretical density (the theoretical density of Li 2 TiO 3 ρ T is 3.43 g/cm 3 ). It can be seen that when the sintering temperature is 1000, 1050, and 1100 • C, the crushing load and relative densities first increase and then decrease.…”

“…With the installation and the start of the significant project of the international thermonuclear fusion experimental reactor program in the French headquarters in 2020, [1][2][3][4][5] the Test Blanket Module (TBM) in various countries has gradually entered the technical research and development stage from the design description stage. [6][7][8][9] The research of tritium breeder, which is the functional material of the TBM, has also become more professional and refined, namely Li 2 TiO 3 , Li 4 SiO 4 , Li 2 ZrO 3 , LiAlO 2 , Li 2 O, and their composites.…”

Li 2 TiO 3 is considered as one of the best candidates for breeding materials. This article adopted a modification water-based sol-gel method to synthesize nano-Li 2 TiO 3 powders, which overcomes the poor phase purity, coarse grain, and inferior crushing strength described in the previous literature. In this paper, the thermal effect of the precursor, the crystal phase, and the morphology of the powders were characterized by thermogravimetric analysis/differential thermal analysis (TG/DTA), X-ray diffraction (XRD), and transmission electron microscopy (TEM) techniques. The nano-structured Li 2 TiO 3 powders with good dispersion and an average particle size of 20-50 nm were successfully synthesized at 600 • C by controlling PH and hydrolysis rate. Moreover, the phase transition temperature for the monoclinic phase β-Li 2 TiO 3 was as low as 600 • C, which is lower than 750 • C using the traditional solid-state method. Meanwhile, the morphology, porosity, crushing load, and thermal conductivity of ceramic pebbles are characterized systematically by using scanning electron microscope (SEM), mercury injection meter, compression strength equipment, and laser scattering method, respectively. Experimental results showed that the Li 2 TiO 3 ceramic pebbles with a sphericity of .98, crush load of 48.4 N, and relative density of 90.03 % were successfully prepared at 1050 • C for 2 h. This method will provide new guidance for the preparation of tritium breeders.
