As an advanced tritium breeder material for the fusion reactor blanket of the International Thermonuclear Experimental Reactor (ITER), Li₂TiO₃-Li₄SiO₄ biphasic ceramic has attracted widely attention due to its merits. In this paper, the uniform precursor powders were prepared by hydrothermal method, and nanostructured 2Li₂TiO₃-Li₄SiO₄ biphasic ceramic pebbles were fabricated by an indirect wet method at the first time. In addition, the composition dependence (x/y) of their microstructure characteristics and mechanical properties were investigated. The results indicated that the crush load of biphasic ceramic pebbles was better than that of single phase ceramic pebbles under identical conditions. The 2Li₂TiO₃-Li₄SiO₄ ceramic pebbles have good morphology, small grain size (90 nm), satisfactory crush load (37.8 N) and relative density (81.8 %T.D.), which could be a promising breeding material in the future fusion reactor.

Li ₂ TiO ₃ -Li ₄ SiO ₄双相陶瓷作为国际热核实验堆（ITER）聚变反应堆毯层的先进advanced育材料，因其优点而备受关注。本文采用水热法制备了均匀的前驱体粉末，并制备了纳米结构的2Li ₂ TiO ₃ -Li ₄ SiO _4。首次通过间接湿法制造双相陶瓷卵石。另外，研究了它们的微观结构特征和机械性能的组成依赖性（x / y）。结果表明，在相同条件下，双相陶瓷卵石的破碎载荷要好于单相陶瓷卵石的破碎载荷。2Li ₂ TiO ₃ -Li ₄ SiO ₄陶瓷卵石具有良好的形貌，较小的晶粒尺寸（90 nm），令人满意的压碎载荷（37.8 N）和相对密度（81.8％TD），这可能是将来有希望的育种材料。聚变反应堆。
