“…In the emulsion method, [13][14][15] green pebbles with a narrow size distribution are produced by cutting the Li 2 TiO 3 slurry flow with oil flow in a T-shaped flow path. The extrusion spheronization method [16][17][18] forms green pebbles from mixture of raw powder and polyvinyl-alcohol binder using a Spherodizer. Additive manufacturing 19,20 is an emerging technique, which employs ultraviolet light or a CO 2 laser to form green pebbles.…”

A large amount of Li-containing ceramic breeder pebbles is packed in the solid breeding blanket of a nuclear fusion reactor. Several pebble fabrication technologies have been proposed in previous studies, including wet process, emulsion method, extrusion spheronization, additive manufacturing, and melt process.However, a simple, energy-effective, and scalable fabrication technology remains to be developed for the automated mass production and reprocessing of used radioactive pebbles post-operation. Selective laser melting potentially enables the quick and automated fabrication of breeder pebbles. Herein, we employ a high-power density pulse laser to produce ceramic breeder pebbles. A pulsed YAG laser was irradiated over a lithium metatitanate (Li 2 TiO 3 ) powder bed in air, and the corresponding temperature was monitored using fiber-type infrared pyrometers. Spherical Li 2 TiO 3 pebbles were successfully fabricated in a single step with an average diameter of 0.78 ± 0.13 μm and the sintering density of 87.4% ± 5.6% (input power: 7.9 J/pulse). The irradiated Li 2 TiO 3 powder melted and turned spherical under surface tension and rapidly solidified, resulting in uniaxial fine grains and a decrease in the degree of long-range cation ordering.
