| Abstract: | Nanometer sized lanthanum 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 lanthanum oxide on catalyzing thermal decomposition reaction of absorbent powder (nitrocellulose absorbed nitroglycerine,NC/NG) was studied by DSC.The experimental results showed that nanometer sized lanthanum oxide could catalyze the decomposition reaction of NC/NG effectively.The mechanism involving transitional coordination compound of this catalytic reaction was proposed. |
