Abstract
Thermolysis of cesium bis(citrato)ferrate(III) trihydrate, Cs-3[Fe(C6H 5O7)(2)].3H(2)O, has been studied in the temperature range of 373-1073 K in static air atmosphere, using Mossbauer and infrared spectroscopy and thermogravimetric methods. The anhydrous complex decomposed into a n iron(II) intermediate at 453 K and alpha-Fe2O3 of varying particle s izes in successive stages. Finally a solid state reaction between alph a-Fe2O3 and cesium carbonate/oxide gives fine particles of cesium ferr ite (CsFeO2) at a temperature lower than that of conventional ceramic method.
