Magnetite powder was synthesized via chemical co-precipitation method using FeCl3 · 6H2O and FeCl2 · 4H2O as salts and ammonium hydroxide (25% NH4OH) solution as precipitating agent. The phases, composition and morphology of the magnetite was characterized by X-ray diffraction (XRD), micro ...
magnetiteAC heatingMagnetite particles with different average diameter ( D m) suitable for magnetic fluid hyperthermia (MFH) were synthesized by controlled coprecipitation technique. In this method, the reaction pH was stabilized using the pH buffer and the average particle diameter decreased with ...

This paper presents a simple method for the rapid synthesis of magnetite/hydroxyapatite composite particles. In this method, superparamagnetic magnetite nanoparticles are first synthesized by coprecipitation using ferrous chloride and ferric chloride. Immediately following the synthesis, carbonate-substituted (...
In FeIII rich medium, the formation of magnetite Fe3O4 was favoured, but was sometimes preceded by the precipitation of green rusts [12], [15]. It is now well established that in anoxic conditions green rusts are transformed either in a mixture of magnetite and siderite {Fe3O4, FeCO3}...
