由6li同位素富集的钛酸锂由于其优异的性能被认为是聚变反应堆氚增殖材料的候选材料。由于富锂材料的高成本和废物的考虑，燃烧的li2tio3鹅卵石的再利用是一个重要的问题。为此，采用石墨床法对li2tio3鹅卵石进行了再处理。根据预期的锂燃耗量，制备了低锂含量的模拟li2tio3鹅卵石。然后，用碳酸锂作为锂添加剂重新制备li2tio3鹅卵石，得到Li/Ti比为2的钛酸锂成分。对该工艺进行了优化，得到了适于作为陶瓷增殖剂的再加工li2tio3鹅卵石。对再加工鹅卵石的密度、孔隙率、粒度和破碎载荷进行了表征。该工艺不会使再加工鹅卵石的性能恶化，也几乎不会产生废物。
Lithium titanate enriched by6Li isotope is considered as a candidate of tritium breeding materials for fusion reactors due to its excellent performance. The reuse of burned Li2TiO3pebbles is an important issue because of the high costs of6Li-enriched materials and waste considerations. For this purpose, reprocessing of Li2TiO3pebbles by graphite bed method was developed. Simulative Li2TiO3pebbles with low-lithium content according to the expected lithium burn-up were fabricated. After that, Li2TiO3pebbles were re-fabricated with lithium carbonate as lithium additives, in order to gain the composition of lithium titanate with a Li/Ti ratio of 2. The process was optimized to obtain reprocessed Li2TiO3pebbles that were suitable for reuse as ceramic breeder. Density, porosity, grain size and crushing load of the reprocessed pebbles were characterized. This process did not deteriorate the properties of the reprocessed pebbles and was almost no waste generation.
