Potassium hexacyanoferrate(II) trihydrate, K4Fe(CN)6·3H2O, was heated under controlled conditions of mass and rate in a derivatograph in the presence of oxygen. The heating was stopped at different temperatures and Mössbauer spectra and X-ray diffractograms were taken on the quenched material at room temperature. The reaction pathway was studied in this way and the advantages and drawbacks of each of the techniques are described. At different stages of the thermal process we were able to show the presence of K4Fe(CN)6,α-Fe2O3, Fe3O4, Fe3C, Fe, FeO, KFeO2,Β-FeOOH, KOCN, K2CO3 and KCN.
