- W2016207384 abstract "Measurements are reported for pure NaCl crystals of intrinsic ionic conductivity (550°–800°C), diffusion of Na tracers (640°–790°C), and diffusion in a d.c. electric field of Na tracers (600°–770°C) and Cl tracers (690°, 770°C). The diffusion measurements in a field represent the first quantitative application of this technique to alkali halides and afford a direct determination of Na tracer drift mobilities from the observed displacement of the diffusion profile. A general experimental check is provided by showing that the sum of the cation and anion mobilities agrees with the total conductivity.The results can be interpreted satisfactorily in terms of contributions to diffusion of both cations and anions from both free vacancies and neutral vacancy pairs. The best fit of all available conductivity, diffusion, and mobility data gives Dv∗(Na) = 182 exp (−2·10kT) and Dpr∗(Na) = 1130 exp (−2·35kT), with D0 in cm2sec and W in eV; vacancy pairs contribute nearly 40 per cent of the Na diffusion at the melting point. This fit gives an essentially constant anion transport number of 0.34 and an activation energy for cation diffusion by single vacancies of 2.10 eV; both of these are noticeably larger than previous values. It is also found that Dpr∗(Na) is 6 to 7 times larger than Dpr∗(Cl), just slightly above the limit imposed by the theory of correlation factors, which means that cation jumps into a vacancy pair have a much higher frequency than anion jumps, contrary to theoretical predictions. The diffusion data for vacancy pairs are not compatible with previously reported high temperature dielectric loss measurements. These data also rule out any appreciable contribution from cation Frenkel defects, but difficulty in fitting the conductivity suggests that vacancy triplets may make a small contribution." @default.
