“…12,13 Extensive efforts have been devoted to developing universal and efficient methods for the preparation of size-controllable tritium breeder pebbles. The mainstream methods for breeder ceramic pebble preparation can be classified into extrusion-spheronizationsintering, [14][15][16][17] rolling method, [18][19][20] melt spraying, [21][22][23][24] and wet process. [25][26][27] In the extrusion-spheronizationsintering process, the conventional method is to extrude rod-like semi-solid billets consisting of organic binder and ceramic powder from the extrusion equipment and then granulate it with a spheronizer under the action of friction.…”

Wet methods as an emerging technique for the preparation of millimeter‐sized tritium breeding ceramic pebbles, but the imposed air pressure as the driving forces to extrude slurry droplets are fluctuating during the reciprocating extrusion process, which caused a slight inconsistency in pebble sizes. In this study, a piezoelectric micro‐droplet jetting approach was proposed by introducing a piezo‐driven valve and modifying the slurry barrel mechanism to realize the air pressure invariable. A self‐developed piezoelectric micro‐droplet jetting device was successfully utilized to prepare Li2TiO3 green pebbles with coefficients of variation being lower than 2.7%. The size of the green pebbles could be precisely controlled in the range of 0.88–1.37 mm by manipulating the nozzle diameter, the air pressure, and the jetting time. The pebbles sintered at 1000°C for 3 h possessed a small grain size of ∼5.9 μm, a satisfied relative density of ∼84.8% T.D., and a high crush load of ∼25.7 N, implying the prepared pebbles could be used as a promising solid tritium breeding material in fusion reactors. These findings are anticipated to provide new opportunities for the highly efficient preparation of size‐controllable tritium breeding ceramic pebbles.

The thermal annealing effect on the morphological, structural and electrochemical properties of hydrothermal synthesized Li4Ti5O12 / TiO2 has been studied. Lithium titanate (Li4Ti5O12) nanopowders are successfully synthesized by hydrothermal method using titanuim tetrabutyl and lithium hydroxide followed by thermal annealing process at different temperatures: 500°C, 800°C and 900°C.The X-ray diffraction (XRD) patterns indicates the appearance of the Li4Ti5O12 phase at a temperature above 800°C formed after the reaction of the two phases: TiO2 and Li2TiO3 which appear at 500°C. Though, the prepared electrode by the powder annealed at 800 °C shows an initial capacity of about 173.1 mAh/g (0.1 C), which retained at 75.6 mA h/g after 100 cycles.
