Thermal Decomposition Process of FeC2O4. 2H2O in the Air

Abstract

α-Fe2O3 nanoparticles are prepared at 550 °C by the thermal decomposition of FeC2O4·2H2O in the air. The morphologies of the pyrolysates of FeC2O4·2H2O in the air were investigated by scanning electron microscope (SEM). The results showed that in the process of the thermal decomposition of FeC2O4·2H2O, the influence on the pattern of the decomposition was more from 249.9 °C to 550 °C. The influence on the pattern of the decomposition was less from 218.4 °C to 249.9 °C. Therefore, the thermal condition of FeC2O4·2H2O in the air was controlled if the effective pattern of α-Fe2O3 powder was obtained.
