Solid-fuel rocket propellants comprising an oxidizer, an oxophilic metal-halophilic metal formulation, and a binder are described herein. Further described are processes for preparing such propellants and methods of reducing hydrogen chloride production via the combustion of such propellants. Non-limiting examples of such formulations include aluminum-lithium alloys.

A method continuously produces emulsion explosive by emulsification and sensitization in a static state without a loading pump. After the water phase and oil phase enters a static emulsifier for emulsification, the emulsion enters a static sensitization device; the sensitizer enters the static sensitization device through the sensitizer charging inlet and mixes with the emulsion in the static sensitization device. After emulsification and sensitization, the sensitized explosive directly enters an injection pipe for encapsulation. By adopting the static emulsifier and sensitization device, the explosive material storage amount is greatly reduced, and mechanical stirring and shearing for emulsification is avoided. Meanwhile, mechanical mixing for sensitization is omitted and replaced with full-static high-temperature sensitization, and the safety of sensitization is improved. The loading pump is omitted, and the sensitized emulsion directly enters the injection pipe, thus the risk points in the production process and the online explosive material storage amount are reduced.

Explosive compositions including coated urea and an explosive including ammonium nitrate and fuel oil are provided. The explosive compositions can generate reduced levels of nitrogen oxide upon detonation. Methods of loading a blasthole with the explosive compositions and methods of reducing post-blast nitrogen oxide are also provided.

A gas propelled munitions anti-fouling system has a case having an open forward mouth end, a rear end, and an interior, the rear end defining a pocket that receives a primer and a passage communicating between the pocket and the interior of the case, a quantity of propellant received within the interior of the case, a quantity of anti-fouling composition received within the interior of the case, and a bullet having a rear portion inserted into the open forward mouth end of the case. The anti-fouling composition may have at least one salt and at least one acid. The acid may be anhydrous. The salt may be sodium chloride or sodium nitrate. The acid may be anhydrous citric acid. The anti-fouling composition may have at least one abrasive. The abrasive may be stannic acid. The anti-fouling composition may be 50% salt by weight and 50% acid by weight.
