• 一般注記: Ammonium nitrate (AN) shows promise as a gas generator component because of its affordable price. However, handling this compound is problematic because it is highly hygroscopic and hence undergoes aggregation and solidification. In this study, in order to prevent the hygroscopicity of phase-stabilized ammonium nitrate (AN/KN), we prepared particles from a combination of AN/KN and a polymer (moisture-proof agent) by the spray drying technique and investigated the hygroscopicity. A white powder with a particle diameter of about 20-40microns was successfully prepared by spray drying water solutions (or water dispersions) containing AN/KN and each of the three types of polymers. The results of elemental analysis by Scanning Electron Microscope/Energy Dispersive X-ray spectrometry (SEM/EDX) indicated that each component was homogeneously distributed in the particles. Particle aggregation was hardly observed, and the moisture absorption amount was lower than that in the case of the polymer-free (blank) sample. Evn under high-moisture conditions, the particles did not deliquesce immediately and retained their original shape, unlike the blank sample.; 形態: カラー図版あり; Physical characteristics: Original contains color illustrations; 資料番号: AA0061907004; レポート番号: JAXA-RR-12-005
