Abstract

Thermal analysis of zinc hexa(formato)ferrate(III) decahydrate, Zn3 [Fe(HCOO)6]2 10H2O has been investigated up to 800°C in static air atmosphere employing TG, DSC, XRD, IR, ESR and Mössbauer spectroscopic techniques. After dehydration at 160°C, the anhydrous complex decomposes into α-Fe2 O3 and zinc carbonate in successive stages. Subsequently the cations remix to yield fine particles of zinc ferrite, ZnFe2 O4 , as a result of solid state reaction between α-Fe2 O3 and zinc carbonate at a temperature (600°C) much lower than for ceramic method.
