The new way of calculation of segregation enthalpy on the basis of grain boundary diffusion data is offered. It proceeds from the primary data on an interval "B"- regime of grain boundary diffusion. For data processing we used the expression for coefficient of grain boundary diffusion got by Borisov and Lubov according to Fisher model for a tail part of the concentration curve. To approve this approach the data of tellurium diffusion in grain boundary of polycrystalline silver are considered.
