A radiation curable energetic composition that can be used, for example, to form pyrotechnic energetic components. The energetic composition includes a radiation curable polymer precursor and a pyrotechnic. The energetic composition may be dispersed in a liquid vehicle to facilitate deposition of the energetic composition using direct-write techniques.

The present invention is a red-light-emitting composition based upon a potassium periodate oxidizer formulation, which is useful as the illuminant in the US military's M662 40 mm red star parachute projectile, and which composition is composed of readily commercially available ingredientsingredients that are environmentally friendly. Further, the subject inventive potassium periodate formulation provides significant enhanced illumination and safety versus the current military M662 illuminant which is based upon potassium perchlorate oxidizer formulation.

An ignition composition comprising a low electron affinity material, an oxidizer and a binder. The ignition composition may be made by A1) preparing a coagulation composition by a shock-gel process using the ingredients of the ignition composition disclosed herein, which comprises: A1-a) dissolving the binder in a low-boiling-point polar solvent to provide a binder solution; A1-b) mixing the low electron affinity material and the oxidizer with the binder solution; and A1-c) adding a low-boiling-point non-polar solvent to the mixture provided by step 1-b) to precipitate the binder and form the coagulation composition; and A2) converting the coagulation composition into granular composition using a suitable method.
