Nanometer sized ferric oxide was synthesized at room temperature by humid solid state reaction. The particles were characterized by scanning electron microscope and X ray diffraction. The effect of nanometer sized ferric oxide on catalyzing thermal decomposition reaction of absorbent powder (nitrocellulose absorbed nitroglycerin, NC/NG) was studied by DSC. The experimental results show that nanometer sized ferric oxide can catalyze the decomposition reaction of NC/NG effectively. The mechanism of this catalytic reaction was proposed.
