Rapid Millifluidic Synthesis of Stable High Magnetic Moment FeC Nanoparticles for Hyperthermia.

A millifluidic reactor with a 0.76 mm internal diameter was utilized for the synthesis of monodisperse, high magnetic moment, iron carbide (FeC) nanoparticles by thermal decomposition of iron pentacarbonyl (Fe(CO)) in 1-octadecene in the presence of oleylamine at 22 min nominal residence time. The effect of reaction conditions (temperature and pressure) on the size, morphology, crystal structure, and magnetic properties of the nanoparticles was investigated.
