- 出版タイプ: NA本研究ではAN/AP系推進薬に関する基礎研究として、スプレードライによりANおよびAPが一体化した粒子を調製し、SEMによる表面状態の観察およびTG-DTAによる熱分析を実施した。SEM観察の結果、ANの吸湿に由来する凝集が観察されたものの、概ね球状の粒子が観察された。平均粒子径は36-38μmであった。TG-DTA測定の結果では、重量減少を伴う吸熱が130-230 および280-375 C付近に観察され、280-375 C付近に発熱が観察された。ANおよびAP単独との比較から,吸熱ピークは、それぞれの熱分解に由来することが示唆された。一方、発熱ピークはANおよびAP単独では観察されず、AN/AP混合粒子のみで観察されることから、ANとAPの反応に由来すると考えられる。また、AN単独の場合、相転移に由来する吸熱ピークが43、 90 および 125 C付近に観察されるが、AN/AP混合粒子では、90 CのピークがANと比較して非常に小さくなる等、結晶構造の変化を示唆する結果が得られた。In this study, we prepared ammonium nitrate (AN)/ ammonium perchlorate (AP) mixed particle using spray drying for the fundamental study on AN/AP-based propellants. We investigated their surface properties and thermal behavior by scanning electron microscopy (SEM) and thermogravimetry/differential thermal analysis (TG/DTA) respectively. In the result of SEM analysis, the shape of the AN/AP particles was almost spherical. In some cases, particle partially aggregated because of moisture absorption by AN. The average particle diameter was approximately 36-38 μm. In the result of TG/DTA, endothermic peaks were observed around 130-230 and 280-375 C and exothermic peak was observed around 230-280 C. From the comparison with the result of AN and AP, it is considered that endothermic peaks were caused by each thermal decomposition. On the other hand, we suggest that the exothermic peak may result from the reaction between AP and AN because it is only observed in the curves of AN/AP. Endothermic peaks derived from crystal structure transformation of AN were observed around 43, 90 and 125 C by thermal analysis of AN and AN/AP. The peak around 90 C of AN/AP was extremely smaller than that of AN, and this suggested that crystal structure of AN might be changed.
