The Measurement of Self-Diffusion in Zinc

Abstract

Measurements of self-diffusion along the $C$ axis of zinc single crystals have been carried out. Long-lived radioactive ${\mathrm{Zn}}^{65}$ was used as an indicator. Measurements were made at six different temperatures, enabling a determination of the activation energy, which is 19,600 calories per mol. The diffusion coefficient at 410.4°C is 9.89×${10}^{-4\mathrm{}}$ ${\mathrm{cm}}^2$/day.
