Abstract: Nanometer-CuO powder was synthesized by solid-state reaction using CuCl 2·2H 2O 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 ℃ 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.
