Abstract
The diffusion coefficients of silver in molten copper at infinitly high dilution have been studied within the temperature range of 1143°∼1290°C by the use of capillary method and Ag110 as radioactive tracer. The obtained results can be represented by D_Ag in Cu = (1.93±0.43)×10^-3 exp(-11210±285/RT) cm^2/secThe dependence of diffusion coefficients of silver in Cu-Ag system upon the concentration has been studied at the concentration of silver, NAg=0.146 and in the temperature range of 1150°∼1311°C. The obtained results can be represented by D_Ag in Cu-Ag (N_Ag = 0.146) = (6.81±1.96)×10^-4 exp(-9030±330/RT) cm^2/sec.
