• Note (General): 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.
