Expressions, originally presented by Humphreys and Mason, are extended to indicate that accurate binary diffusion coefficients, D12, may be predicted over a large range of temperatures from one value of D12 and a value of the thermal diffusion factor, αT, at the same temperature. For those systems which have thermal diffusion factors which are relatively insensitive to temperature, the predicted diffusion coefficients are very accurate for a range of temperatures much greater than that used for the thermal diffusion measurements. © 1995 American Institute of Physics.
