“…The peak positions and relative intensities of the XRD patterns can be seen at 2θ = 30.08°, 35.42°, 43.06°, 56.94°, 62.52° and 74.96°, which are the reflection peaks from the (220), (311), (400), (511), (440) and (533) lattice planes. These iron oxide particle XRD patterns are in good agreement with the standard magnetite particle XRD patterns [18,[21][22][23][24][25]. At these conditions, the magnetite particles are generated by the following reactions: ferric hydroxide (Fe(OH) 3 ) is transformed to ferrous hydroxide (Fe(OH) 2 ) grows on goethite (FeOOH).…”

Abstract. Magnetite particles were successfully generated by hydrothermal synthesis using water at subcritical conditions. By changing the temperature and pressure at subcritical water conditions, the thermodynamics and transport properties of the water can be controlled, thus enabling to manage the way of crystal formation, morphology, and particle size. In this work, the experiments were carried out at temperatures of 250 °C and 290 °C and a pressure of 10 MPa with a reactor made of SUS 316 in a batch system. The synthesized particles were dried in vacuum condition and characterized by SEM and XRD. The XRD patterns showed that magnetite particles were dominantly formed in the particle products with a black color. The results showed that the magnetite particles formed had diameters of around 60 nm in all experiments with irregular polyhedral shaped morphologies.

Superparamagnetic iron oxide nanoparticles were obtained in the polyethylene glycol environment. An effect of precipitation and drying temperatures on the size of the prepared nanoparticles was observed. Superparamagnetic iron oxide Fe 3 O 4 , around of 15 nm, was obtained at a precipitation temperature of 80 o C and a drying temperature of 60 o C. The presence of functional groups characteristic for a polyethylene glycol surfactant on the surface of nanoparticles was confi rmed by FTIR and XPS measurements. Silver nanoparticles were introduced by the impregnation. Fe 3 O 4 -Ag nanostructure with bactericidal properties against Escherichia coli species was produced. Interesting magnetic properties of these materials may be helpful to separate the bactericidal agent from the solution.

“…The magnetite nanoparticles prepared by this method have a long-term stability and are easily coated by various materials to generate multifunctional nanoparticles. Nonaggregated magnetite nanoparticles have been already synthesized in liquid polyols at elevated temperature (Cai et al, 2007). Highly performance magnetite nanoparticles have been also obtained by a modified polyol process.…”
