摘要
用DSC方法研究了高氯酸铵 (AP)、高氯酸钾 (KP)、AP/KP(质量比分别为 1/ 1和 3/ 1)体系的热分解特性和一些过渡金属氧化物对上述体系热分解反应的催化作用。结果表明 ,AP/KP混合氧化剂的DSC曲线是AP和KP热分解曲线的叠加 ,但AP的放热分解使KP的热分解过程提前 ,钴氧化物和铜氧化物对上述氧化剂体系的热分解反应有显著的催化作用。
The thermal decomposition characteristics of ammonium perchlorate (AP),potassium perchlorate (KP) and their mixtures of AP/KP 1/1 and 3/1 were respectively studied by DSC,and the influence of some transition metal oxides on the thermal decomposition of the said oxidizers were studied as well. The experimental results show that the DSC curves of AP/KP mixture are the overlap of those of AP and KP. The exothermic decomposition of AP in AP/KP mixture moves up the onset of KP decomposition at lower temperature. Both CoO/Co 2O 3 and CuO catalyze the thermal decomposition of AP,KP and their mixture.
