近年来，钛酸锂（Li 2 TiO 3）因其低温下良好的氚回收率、化学稳定性等优点而引起了众多研究者的关注。由于Li 2 TiO 3的形状，日本设计的聚变反应堆包层选用了小卵石。另一方面，作为Li 2 TiO 3微珠的制造方法，从批量生产等的观点来看，湿法工艺是最有利的。在本研究中，通过具有置换反应的湿法工艺来制造小于0.5mm的小Li 2 TiO 3微珠，并且评价通过该工艺制造的Li 2 TiO 3微珠的特性。从制备试验的结果来看，具有目标密度（80- 85% T.D.）的Li_2TiO_3小球的批量生产具有良好的前景。和目标直径（小于0.5mm）。
Recently, lithium titanate (Li2TiO3) has attracted the attention of many researchers from the point of good tritium recovery at low temperature, chemical stability, etc. As the shape of Li2TiO3, a small pebble was selected as the Japanese design for a fusion reactor blanket. On the other hand, as the fabrication method of Li2TiO3pebbles, the wet process is the most advantageous from the viewpoint of mass production, etc. In this study, fabrication of small Li2TiO3pebbles less than ∅0.5 mm was performed by the wet process with substitution reaction, and the characteristics of Li2TiO3pebbles fabricated by this process were evaluated. From the results of the fabrication tests, excellent prospects were obtained concerning mass production of Li2TiO3pebbles with the target density (80–85% T.D.) and target diameter (less than ∅0.5 mm).
