锂基陶瓷一直被认为是聚变堆包层的有前途的氚增殖材料。特别地，它们的高热稳定性和化学惰性是有利的安全特性。候选陶瓷增殖材料的最重要的资格是最有可能承受高温和大温度梯度下长期辐照的严酷条件的能力。作为一个群体，锂基陶瓷显示出良好的辐照行为和优异的氚释放特性。个别材料的性能将取决于实际应用，即卵石床与颗粒的概念，较高与较低的冷却温度等。最近，Li2ZrO3和Li2TiO3被选为增殖材料的ITER增殖毯由于其优异的氚释放行为在低温下。将突出强调为支持目前的毯子设计研究而正在处理的问题。(C)1998年Elsevier Science S.A. All rights reserved.
Lithium-based ceramics have long been recognized as promising tritium-breeding materials for fusion reactor blankets. In particular, their high thermal stability and chemical inertness are favorable safety characteristics. The most important qualification for a candidate ceramic breeder material is most likely, the ability to withstand the rigors of long-term irradiation at high temperature and under large temperature gradients. As a group, the lithium-based ceramics have shown good irradiation behaviour and excellent tritium release characteristics. Individual materials performance will depend upon the actual application, namely, pebble bed versus pellet concept, higher versus lower cooling temperature, etc. Recently Li2ZrO3 and Li2TiO3 were selected as the breeder material for the ITER breeding blanket due to their excellent tritium release behaviour at low temperature. Issues being addressed in support of current blanket design studies will be highlighted. (C) 1998 Elsevier Science S.A. All rights reserved.
