To obtain better understanding of thermal decomposition characteristic of FOX-12, this paper focused on analysis of initial decomposition of FOX-12 using in situ measurement with differential scanning calorimetry (DSC) and sample observation or Raman spectrometry for understanding decomposition characteristic of FOX-12. We conducted Raman spectroscopic analysis and sample observation during thermal analysis at 1 and 8 C min-1. The experiment results found that thermal behavior of FOX-12 was different by heating rate and formed condensed phase before sharp exotherm at high heating rate. For DSC/Raman result indicated guanidium nitrate (GN) and cyanuric acid formed during thermal decomposition of FOX-12. From observation results, GN and cyanuric acid formed with solid phase reaction of initial decomposition. And the molten GN affects the precipitous exothermal reaction of FOX-12., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2030016006, レポート番号: JAXA-RR-20-007}, title = {熱分析とその場観察および分光分析に基づくFOX-12の熱分解特性解析}, year = {2021} }
