摘要：

The self-diffusion coefficient of lithium ion in Li2O was determined in the range 515-1288°C by means of the sectioning technique using 6Li as the tracer. The Arrhenius relation was represented by D = 4.06 × 103exp( -58.2 × 103 RT) cm2 s above 1000°C and by D = 3.25 × 10-3exp( -23.4 × 103 RT) cm2/s below 1000°C. The characteristics of lithium diffusion in Li2O, which is antifluorite cubic, was discussed in comparison with anion diffusion in CaF2 and other fluorite-cubic crystals. © 1979.
