摘要：

Diffusion of lithium ion and tritium in octalithium plumbate (LisPbO6) was studied. The electrical conductivity of the polycrystalline pellets measured by the two‐terminal ac method in the temperature range of 300 to 973 K was one of the highest among oxide lithium ceramics. The temperature dependence of the conductivity is consistent with the nuclear magnetic resonance of lithium‐7 powder samples, suggesting that the temperature dependence of the diffusion of lithium consists of three regions in this temperature range. Preliminary measurements of the diffusion coefficient of tritium in neutron‐irradiated LisPbO6 powder were also carried out. The results were compared with the diffusion of lithium ion, and the relationship between diffusion of lithium ion and tritium is discussed. Copyright © 1990, Wiley Blackwell. All rights reserved
