    Abstract: A process for producing fine-grained .beta.-HMX wherein a solution of .beta.-HMX is treated in a .gamma.-lactone in a temperature range of between 5.degree. and 15.degree. C. with toluene, and the desired fine and very pure .beta.-HMX crystals are precipitated. The resultant crystals have grain sizes of down to 5 .mu.m and exhibit an extremely small proportion of other modifications or forms of HMX. An additional aspect of the process resides in providing the very fine .beta.-HMX with a coating of a thermoplastic polymer. In this procedure, the .beta.-HMX particles, after having been separated from toluene, are made into a slurry in water and combined under agitation at temperatures of between 25.degree. and 60.degree. C. with a solution or suspension or emulsion of the thermoplastic polymer. During this step, granules are formed which can be separated after distillation of the solvent.

    Abstract: A method for producing porous propellant charges from a mixture containing a propellant and a filler is described wherein a propellant having a decomposition temperature above 200.degree. C. is employed with a thermally removable filler to provide the charge forming mixture. The mixture is molded into a charge body and is subsequently heated to remove the filler at a temperature that is at least 50.degree. C. below the decomposition temperature of the propellant. Due to the heating at the elevated temperature the filler is wholly or in part removed to form a cavity within the charge body.

    Abstract: An electrically primable igniter charge yield has a composition that yields a reduced proportion of toxic vapors after the deflagration. The composition of the charges contains, as the oxidizing agent, zinc peroxide and, as a component providing additional energy, initiating explosives of the kind which do not trigger a detonation in direct contact with press-molded elements of nitrocellulose propellant charge powders. Among these initiating exposives are the potassium salts of trinitrophenol or trinitroresorcinol. The components of the igniter charges are mixed with fibers of an electrically conductive material. Suitable conductive materials are carbon or metals, such as iron or copper, or metal alloys, such as brass, for example. The igniter charges furthermore contain a binder which is preferably a secondary explosive, such as, for example, nitrocellulose.
