To investigate solid‐solution formation in the iron‐doped silicate (zircon) system, different samples were prepared by the ceramic method with addition of LiF as a mineralizer. The results of X‐ray powder diffraction (XRD), 57 Fe Mössbauer, and UV–visible spectroscopy showed that in the as‐prepared samples, only a small fraction of iron, i.e., about 2.5 mol%, is hosted in the zircon structure as paramagnetic Fe 3+ species, while the remaining Fe 3+ cations form magnetic α‐Fe 2 O 3 particles that are trapped in the zircon matrix.
