The aim of the study was to characterize the 0.8CaZrO
3
-0.2CaFe
2
O
4
composite structure with particular emphasis on the role and position of iron in the function of sintering temperature. The paper presents the results of
57
Fe Mössbauer effect at room temperature. It was found that the increase of sintering temperature causes an increase in the amount of incorporated iron ions in the CaZrO
3
-crystal structure. Based on Mössbauer spectroscopy analysis, it was found that three different environments of Fe
3+
ions were observed in the obtained materials. Two of them corresponded to CaFe
2
O
4
phase and one was associated with the substitution of Zr
4+
by Fe
3+
in the CaZrO
3
structure.
