The preparation of three different shapes a-Fe2O3 nano-particles by means of force hydrolyzation was discussed in this paper. By controlling the experimental conditions (Fe3+ concentration, acidity, reaction time, reaction temperature etc.), the particles with different shapes (ellipsoidal, pseudocubic, sphere) were obtained.
