在日本设计的聚变包层中，一个小鹅卵石被选为钛酸锂（Li 2 TiO 3）的形状。在本研究中，Li 2 TiO 3卵石的制造试验进行了两种间接湿法工艺（湿法工艺使用的脱水反应和另一种湿法工艺使用的取代反应），和每种Li 2 TiO 3卵石的基本特性进行了评价与日本材料试验堆（JMTR）的辐照试验。从制备试验和表征结果来看，这两种间接湿法工艺在批量生产直径为0.2-2.0mm、密度为理论密度（TD）的80-85%的Li_2TiO_3小球方面具有良好的前景。
A small pebble has been selected as the shape of lithium titanate (Li2TiO3) in the Japanese design of the fusion blanket. In the present study, fabrication tests of Li2TiO3pebbles were carried out by two kinds of indirect wet processes (a wet process using a dehydration reaction and another wet process using a substitution reaction), and the basic characteristics of each kind of Li2TiO3pebbles were evaluated for irradiation tests with the Japan Materials Testing Reactor (JMTR). From results of the fabrication tests and characterization, bright prospects were obtained concerning mass production of Li2TiO3pebbles with a target diameter of 0.2–2.0mm and a target density of 80–85% theoretical density (TD) by these two kinds of indirect wet processes.
