摘要：
alpha-Fe2O3 nanoparticles are prepared at 550 degrees C by the thermal decomposition of FeC2O4 center dot 2H(2)O in the air. The morphologies of the pyrolysates of FeC2O4 center dot 2H(2)O in the air were investigated by scanning electron microscope (SEM). The results showed that in the process of the thermal decomposition of FeC2O4 center dot 2H(2)O, the influence on the pattern of the decomposition was more from 249.9 degrees C to 550 degrees C. The influence on the pattern of the decomposition was less from 218.4 degrees C to 249.9 degrees C. Therefore, the thermal condition of FeC2O4 center dot 2H(2)O in the air was controlled if the effective pattern of alpha-Fe2O3 powder was obtained.
