Abstract
Chemical behavior of tritium produced in octa-lithium plumbate (Li 8PbO 6) crystals by the 6Li(n, α)T reaction has been investigated. Nearly 100% of the tritium in the crystals existed in the T + state. When the neutron-irradiated crystals were heated up to 1073 K under vacuum, almost all the tritium released in the chemical form of tritiated water (HTO(g)). The HTO(g) release rate was controlled by diffusion of tritium (T) in the crystals and the diffusion coefficient ( D) determined in the temperature range from 580 to 670 K was D = 1.1 × 10 −4 exp{−75.5( kJ mol −1)/ RT} cm 2 s −1. The observed tritium diffusivity in Li 8PbO 6 was the largest of the lithium-based oxide ceramics previously reported. This coincides with the fact that the diffusivity of lithium ion in crystals was the largest of these ceramics.
