Single-crystal star-like arrayed particles of hematite: Synthesis, formation mechanism and magnetic properties

Using urea as a precipitation agent, star-like arrayed hematite (α-Fe 2O 3) particles were prepared by a facile precipitation–oxidation reaction in an aqueous solution containing ceyltrimethylammonium bromide at 80 °C. The particles were characterized by powder X-ray diffraction (XRD), field emissio...
