Factors that may influence the micro-emulsion synthesis of nanosize magnetite particles

Effect of ferrous/ferric ions molar ratio on reaction mechanism for hydrothermal synthesis of magnetite nanoparticles

“…Various methods for preparing magnetite nanoparticles have been developed. Liquid phase methods, for example, micro-emulsion (Zhou et al 2001;Gotić et al 2007), thermal decomposition of iron complex in an organic solvent (Park et al 2004), and co-precipitation from the Fe 2+ / Fe 3+ -mixed salt solution in an alkaline medium (Wang et al 2007), are useful among them because they can prepare magnetite nanoparticles quite easily with homogeneous properties. However, the liquid phase methods have some problems.…”

Investigation of solid phase upon γ-irradiation of ferrihydrite-ethanol suspension

“…Recently, Gotić et al (2007Gotić et al ( , 2009) have shown that the g-irradiated ferrihydrite nanoparticles formed in a microemulsion easily and quantitatively transform to magnetite nanoparticles. One of the reasons for such quantitative transition of ferrihydrite to magnetite is the perfect dispersion of water droplets (i.e.…”

Synthesis protocol influence on aqueous magnetic fluid properties

“…Various synthesis methods, adequate for magnetic nanoparticle preparation have been described in literature, like chemical coprecipitation [7,8], sonochemical reactions [9], sol-gel [10], microwave heating [11], mechanochemical [12], micelle microemulsion [13,14] or solvothermal reduction [15]. Compared to other methods, chemical routes have often been found as most convenient methods used for the production of high quality magnetic nanoparticles.…”
