- Synthesis of γ-Fe2O3 by thermal decomposition of ferrous gluconate dihydrate
-
Ferrous gluconate dihydrate (FeC12H22O14·2H2O), was prepared and its thermal decomposition was studied by means of simultaneous thermal analysis, supplemented with a two probe d.c. electrical conductivity measurements under the atmospheres of static air, dynamic air and dynamic nitrogen. Under all the atmospheres final product was found to be α-Fe2O3 with FeO, γ-Fe2O3, Fe3O4 etc. as probable intermediates. γ-Fe2O3 was formed under the atmosphere of dynamic air containing water vapour. γ-Fe2O3 thus synthesised was characterised for its structure, morphology, thermal and magnetic behaviour.
