Self-Diffusion in Silver

Abstract

Self-diffusion coefficients in single crystals of pure silver were determined between 630°C and 935°C. The results can be expressed by $D=0.40\mathrm{}\exp (-\frac{44090}{\mathrm{RT}})$ ${\mathrm{cm}}^2$/sec. The activation energy agrees with the value extrapolated from the results of diffusion in impure silver crystals.
