Abstract Ageing is an irreversible process during which, the material undergoes a series of slow chemical degradation/oxidation reactions. The aim of this paper is to study the effect of ageing of ammonium perchlorate-copper chromite (AP-CC) pellets on the burn rate. It also focuses on any change in CC properties due to direct contact with an oxidizer (AP). Accelerated ageing with cyclic temperature profile has been used to replicate the natural ageing. The effect of ageing of individual ingredients on the burn rate was studied. The burn rate of AP-CC pellets was found to reduce when AP-CC were aged together. X-ray diffraction (XRD) and Energy Dispersive Spectroscopy (EDS) analysis were used to identify the change in properties of copper chromite during ageing.

老化对高氯酸铵与亚铬酸铜添加剂燃烧的影响

摘要 老化是一个不可逆的过程,在此过程中,材料会经历一系列缓慢的化学降解/氧化反应。本文的目的是研究高氯酸铵-亚铬酸铜(AP-CC)球团老化对燃烧速率的影响。它还关注由于与氧化剂 (AP) 直接接触而导致的 CC 特性的任何变化。具有循环温度曲线的加速老化已被用于复制自然老化。研究了单个成分的老化对燃烧率的影响。当 AP-CC 一起老化时,发现 AP-CC 颗粒的燃烧速率会降低。X 射线衍射 (XRD) 和能量色散光谱 (EDS) 分析用于确定亚铬酸铜在老化过程中的性能变化。
