Synthesis and Characterization of Nanometer-Size Fe3O4 and γ-Fe2O3 Particles. -Clear transparent hydrosols of magnetite with Fe3O4 particles of less than 10 nm diameter are prepared from aqueous FeCl3-FeCl2 solutions with a molar ratio of Fe(II)/Fe(III) = 0.5 and pH 11-12 without use of a surfactan
## Abstract In this study, magnetite (Fe~3~O~4~) nanoparticles with a size range of 8–20 nm were prepared by the modified controlled chemical coprecipitation method from the solution of ferrous/ferric mixed salt‐solution in alkaline medium. In the process, two kinds of surfactant (sodium oleate and
