The diffusivity of Ag atoms in solid silver metal is 1.0X1017 m 2/s at 500oC and 7.0x10-13 m /s at 1000oC. WebThe self-diffusion coefficient is computed from the interdiffusion coefficient of two isotropically different species or from tracer diffusion, where a labeled ion in tracer amount diffuses in a large excess of another electrolyte of the same ion. The diffusion coefficient Di of the species X i is given by the expression (93)
WebAn experimental study of self-diffusion in polycrystalline silver has been carried out using the radioisotope Ag-110. The electrolytic sectioning technique was used for measuring. … According to IUPAC definition, self-diffusion coefficient is the diffusion coefficient of species when the chemical potential gradient equals zero. It is linked to the diffusion coefficient by the equation: Here, is the activity of the species in the solution and is the concentration of . This term is commonly assumed to be equal to the tracer diffusion determined by watching the movement of an isotope in the material of interest.
