A sensitized explosive that comprises an explosive precipitated onto a sensitizer. The explosive is CL-20, PETN, RDX, HMX, or mixtures thereof and the sensitizer is aluminum, titanium, zirconium, magnesium, melamine, styrene, lithium aluminum hydride, or mixtures thereof. The sensitized explosive is used in a percussion primer that includes a bismuth compound and a melt binder. The bismuth compound is bismuth oxide, bismuth subnitrate, bismuth tetroxide, bismuth sulfide, or mixtures thereof and the melt binder is a wax having a melting point above ambient temperature, trinitrotoluene, poly(3,3-bis(azidomethyl)oxetane), poly(3-azidomethyl-3-methyloxetane), ethyl-3,5-dinitrobenzoate, or mixtures thereof. A gun cartridge and other primer-containing ordnance assemblies employing the percussion primer are also disclosed. Methods of forming the sensitized explosive and the percussion primer are also disclosed.
A sensitized explosive comprising an explosive selected from the group consisting of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.05,903,11]-dodecane (“CL-20”), pentaerythritol tetranitrate (“PETN”), cyclo-1,3,5-trimethylene-2,4,6-trinitramine (“RDX”), cyclotetramethylene tetranitramine (“HMX”), and mixtures thereof and a sensitizer selected from the group consisting of aluminum, aluminum oxide, titanium, zirconium, magnesium, boron, silicon, melamine, styrene, lithium aluminum hydride, calcium silicide, and mixtures thereof, wherein the explosive is precipitated onto the sensitizer.
