摘要
Nanometer sized neodymium oxide has been synthesized by humid solid state reaction at room temperature, and characterized by scanning electron microscope, laser light scattering and X ray diffraction. The effects of nanometer sized neodymium oxide on catalyzing thermal decomposition reaction of hexogen (cyclotrimethylenetriamine, RDX) and absorbent powder (nitrocellulose absorbed nitroglycerin, NC/NG) have been investigated by DSC method. The mechanism of these catalytic reactions has also been proposed. The experimental results show that nanometer sized neodymium oxide can catalyze the decomposition reaction of RDX and NC/NG effectively. The experimental results further suggest that nanometer sized neodymium oxide is a potentially useful combustion catalyst of nitroamine propellant.
