摘要：

Iron-doped silicate (zircon), prepared by a ceramic method with the addition of UF as mineralizer, was analyzed by X-ray powder diffraction (XRD) and (57)Fe Mossbauer spectroscopy to obtain information on the solid solution formation. The results of X-ray diffraction and Mossbauer spectroscopy have shown that only a small fraction of iron. about 1.5 mol%, is incorporated in the zircon structure as paramagnetic Fe(3+) species while the remaining Fe(3+) cations form magnetic alpha -Fe(2)O(3) particles which are trapped within the zircon matrix.
