| Abstract: | The thermal decomposition
of zinc tris(malonato)ferrate (III) decahydrate has been investigated from ambient
temperature to 600°C in static air atmosphere using various physico-chemical techniques
i. e. simultaneous TG-DTG-DTA, XRD.
Mossbauer
and IR. After dehydration at 190oC, the anhydrous complex undergoes oxidative
decomposition to yield  -Fe2O3
and ZnO at 330°C. Subsequently the cations remix to yield fine particles of
zinc ferrite, ZnFe2O4 as a result of solid state reaction between -Fe2O3
and ZnO at a temperature (400oC) much lower than for ceramic method.
The results have been compared with those of respective oxalates. |
