The thermal decomposition of the chromates FeOHCrO4, KFe3(CrO4)2(OH)6, Fe2(CrO4)3.H2O and Fe2(CrO4)3.3H2O have been studied by thermal analysis and Mossbauer spectroscopy. The possible presence of Fe2O(CrO4)2 as a second phase formed during the decomposition is discussed. Final products in all reactions were oxides of iron(III) and chromium(III). In addition K2Cr2O7 Was present in the reaction products for KFe3(CrO4)2(OH)6.
