Abstract: A series of the iron oxide particles with different morphology were prepared by changing the hydrothermal synthesis conditions, type and addition amount of surfactant. The morphology, size and crystal form of the iron oxide particles were characterized using scanning electron microscopy and X-ray diffraction measurement. The results showed that the reaction temperature, reaction time, pH value and reactant amount could affect morphology and size of the iron oxide particles. The iron oxide particles with sheet-like, cubic, burger-like, shuttle-like, rectangular, walnut-like, hexagonal prism and hollow morphology can be obtained by adjusting the additive type and other experimental conditions. The controllable preparation of the iron oxide particles with different morphology is realized.

Key words: iron oxide, superfine particles, hydrothermal method, morphology, controllable preparation
