The synthesis of monodispersed α-Fe_2O_3 nanoparticles via a hydrothermal process

Monodispersed α-Fe2O3 micro-and nano-particles modified by surfactant with good-crystalline properties have been successfully synthesized via a hydrothermal process.The as-prepared products were characterized by XRD and SEM.The effect on reaction time,reaction temperature,pH and starting mixtures to the morphologies of hematite in the hydrothermal conditions have been studied.
