【摘要】采用固相法制备出了纳米级的氧化钕颗粒。并用溶剂-非溶剂法制备出了Nd2O3/高氯酸铵(AP)复合粒子。XRD、SEM测试结果表明,氧化钕的平均粒径为50nm左右,复合粒子为微米级。对复合粒子中Nd2O3的催化热分解性能(DTA)的测试结果表明,Nd2O3/AP复合粒子可使AP的高温分解峰峰温下降88°C,低温分解峰消失。更多还原

【Abstract】 Nano neodymium oxide has been synthesized by solid reaction at room temperature.The nano-Nd₂O₃/ammonium perchlorate （AP） composite particles have been prepared by a novel solvent-nonsolvent method. XRD and TEM are used to characterize this microstructure. The catalytic effect of nanosized Nd₂O₃ on thermal decomposition reaction of AP in the composite particle has been investigated by DTA method. It is shown that the decomposition temperature of nano-Nd₂O₃ /AP composite at high temperature side decreases （88°C）.更多还原
