Abstract:	Using the Mössbauer effect, we analyse the behaviour of (V₂O₅)_1?x(Fe₂O₃)_x solid solutions with the starting composition x = 1?15 mol.% Fe₂O₃. The number of iron ions dissolved in V₂O₅ lattice depends on the initial composition x of Fe₂O₃ and tends to a maximum value corresponding to 4 mol.% Fe₂O₃. The composition dependence of the quadrupole splitting and isomer shifts is presented.
