金属氧化物对RDX热分解影响的研究

Study on the Effect of Metal Oxide on the Thermal Decomposition of RDX

采用差热分析技术研究了金属氧化物(CuO、CdO、Fe2O3、Cu2O、PbO)对黑索今(RDX)热分解性能的影响.试验结果表明:金属氧化物对RDX的热分解有不同程度的催化作用,当质量分数为1.0%(2.0%催化效果最明显,催化能力比较结果为氧化亚铜与氧化铜接近,其次分别为三硫化二铁、氧化铅、氧化镉.

The effect of different metal oxides (CuO、CdO、Fe2O3、Cu2O、PbO) on the thermal decomposition characteristics of RDX has been investigated by DTA. The results show that these metal oxides have different catalytic activities to the thermal decomposition of RDX. When these additives content are at the range of 1.0%~2.0%, the catalytic effect is the best. The comparative result of catalytic activities of these metal oxides is Cu2OCuO>Fe2O3> PbO>CdO.
