The room temperature Mössbauer spectra of ^{57}Fe were measured for Fe_{1-x}Si_x solid solutions with x in the range 0.01 ≤ x ≤ 0.05. The obtained data were analysed in terms of the binding energy E_{b} between two silicon atoms in the studied materials using the extended Hrynkiewicz-Królas idea. The extrapolated value of E_{b} for x=0 was used to computation of an enthalpy of solution H_{FeSi} of Si in α-Fe matrix. It was found that the H_{FeSi} value is negative or Si atoms interact repulsively. The result was compared with corresponding values given in the literature which were derived from experimental calorimetric data as well as with the value resulting from the cellular atomic model of alloys by Miedema.
