摘要: Abstract The paper presents a method to synthesize α-Fe, γ-Fe, magnetite and hematite through solventless thermal decomposition technique using an organo-metallic compound iron(III)citrate in two different atmospheres (N2 O2) at temperatures the characteristics of these products. solid state reaction has been monitored by non-isothermal thermogravimetry. FT-IR spectra powder XRD pattern decomposed products reveal type materials formed SQUID measurements confirm those. Mossbauer spectroscopic study confirms nature magnetic structure synthesized materials. SEM TEM studies are used shape size particles formed. EDX employed know elemental composition. processes involved synthesis have proposed. present indicates that types iron/iron oxide range nano-scale can be on depending temperature as well atmosphere.
