1. A method for preparing an explosive, comprising:
- combining 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.05,903,11]-dodecane (CL-20) particles having an average particle size not greater than 30 microns with a plasticized binder to form an explosive composition; and
granulating the explosive composition into the explosive, the explosive comprising 85 weight percent to about 96 weight percent of the CL-20 particles and about 4 weight percent to 15 weight percent of the plasticized binder.

Abstract
An explosive composition is provided that includes 85 to about 96 weight percent nitramine, based on the total composition weight, and about 4 to 15 weight percent plasticized binder. At least 80 weight percent of the total composition weight, and more preferably 85 to 96 weight percent of the total composition weight, comprises 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.05,903,11]-dodecane (CL-20) particles having an average particle size not greater than 30 microns as the nitramine. Methods for preparing an explosive from the explosive composition are also provided.

11. A method for preparing an explosive having a total weight, the method comprising:
-
providing an aqueous dispersion comprising epsilon polymorph CL-20 particles, the CL-20 particles having an average particle size not greater than 30 microns;
combining the aqueous dispersion with a lacquer comprising a plasticized binder to form a slurry;
agitating the slurry and removing the lacquer to form coated granules; and
drying the coated granules to provide an explosive having a total weight, the total weight of the dry coated granules comprising 85 weight percent to about 96 weight percent CL-20 and about 4 weight percent to 15 weight percent of the plasticized binder. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
