Abstract (en)

[origin: WO9407813A1] In a process for preparing a powder or explosive precursor product substantially composed of nitrocellulose and at least one crystalline explosive, the crystalline explosive in the aqueous phase is added to the nitrocellulose. In order to achieve a particularly uniform distribution of the crystalline explosive, the explosive is available in a fine crystalline form with a mean particle diameter d50 from 2 to 8 (my)m. The crystalline explosive and the nitrocellulose are first separately stirred in the aqueous phase, then they are brough together while continuing to be stirred.
