本研究的主要目的在於探討添加鈣鈦鑛鐵酸鑭於過氯酸銨中進行熱分解基礎研究，與傳統燃燒催化劑氧化鐵進行比較，並透過固態推進劑樣品之燃燒速度進行大氣中的燃燒驗證。研究中將使用檸檬酸法自行製備鐵酸鑭，並使用熱重分析儀得到重量損失與溫度的關係、引燃溫度以及活化能來評估鐵酸鑭對過氯酸鹽熱分解的影響。另一方面，以環氧樹脂作為燃料和膠合劑、過氯酸銨作為氧化劑，加入上述兩種燃燒催化劑來製作固態推進劑，並建立一套推進劑的製作流程。最後，在大氣中測試固態推進劑樣品的燃燒速度，比較兩者催化劑對燃燒速度的影響。透過本研究，分析並且探討新型燃燒催化劑對過氯酸鹽熱分解的影響，其結果將有助於作為固態燃料推進裝置進一步高效應用的基礎。

The main purpose of this study is to examine the fundamental study on the thermal decomposition of perovskite LaFeO3 adding into ammonium perchlorate, compare it with iron oxide, a conventional combustion catalyst, and verify through the burning velocity of solid propellant samples in the air. LaFeO3 prepared by the citric acid method, and the effect of LaFeO3 on the thermal decomposition of perchlorate was evaluated using a thermogravimetric analysis to determine weight loss and temperature, ignition temperature and activation energy. On the other hand, epoxy resin is used as fuel and binder, ammonium perchlorate is used as oxidant, and the above two combustion catalysts are added to produce a solid propellant, and the propellant production methods have been established. Finally, we test the burning velocity of solid propellant samples in the air. Through this study, the influence of new combustion catalysts on perchlorate thermal decomposition has been analyzed and discussed, and the results will provide as a basis for further efficient applications of solid fuel propulsion systems.
