Iran Journal Article 2010 09 28 Size reduction of high energy materials such as 1, 3, 5, 7-tetranitro- 1, 3, 5, 7-tetraaza cyclooctane (HMX) has considerable influences on improving their explosive characteristics. In this study, nanosized HMX par‌ticles were produced using ultrasonically reprecipitation method by applying water as a safe and accessible antisolvent instead of unsafe conventional methods. SEM photographs revealed that much uniform and low agglomerated spherical morphology can be obtained at low concentration of HMX- acetone solution with low temperature antisolvent. These results are achieved from SEM and TEM photographs and Digimizer - Winks software. https://www.ijnnonline.net/article_3956_0f3c5d0c3666eec8cd311bec6d878915.pdf
