纳米氧化钕的制备及其催化性能的研究

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.
