摘要
以CuCl2 ·2H2 O和NaOH为原料 ,通过室温固相反应制备出纳米CuO粉末 ,产物 (CuO)的平均粒径为10nm左右。用DSC研究了纳米CuO对RDX热分解特性的影响。结果表明 ,纳米CuO对RDX热分解有明显的催化作用 ,它使RDX热分解峰温降低了 12℃ 。
Nanometer-CuO powder was synthesized by solid-state reaction using CuCl2·2H2O with NaOH at room temperature. Average particle sizes of nanometer CuO were about 10 nm. The effect of nanometer CuO on thermal decomposition characteristics of RDX was investigated by DSC. The results show that the peak temperature of thermal decomposition of RDX shifts 12°C downward due to the effect of nanometer CuO. The effect of nanometer CuO on the thermal decomposition characteristics of RDX is different from that of normal CuO.
