| Abstract: | Three kinds of RDX samples with different particle sizes were prepared by spray fining method and dropping method.The samples were characterized by using laser granularity apparatus,specific surface area analyzer and scanning electron microscopy(SEM).The flame sensitivity,slow cook-off thermal sensitivity and thermal decomposition characteristics of RDX samples were tested.The flame sensitivity was characterized with 50% flame height,and the slow cook-off thermal sensitivity was characterized with flash poi... |
