A propellant composition comprises a propellant solvent, a propellant base, and a plurality of metal nanoparticles. A powder or dried propellant composition is formed by removing at least a portion of the propellant solvent. The metal nanoparticles of the plurality of metal nanoparticles are nonionic. The plurality of metal nanoparticles functions to reduce visible light output by the propellant composition during deflagration.

Stabilized, amorphous high energetic compositions having crystallization inhibiting polymers dispersed throughout the solid composition. The compositions disclosed herein are an improvement over crystalline high energetic compositions in that such disclosed compositions are stable and possess physical properties desirable in propellant and high explosive applications.

A method of producing K.sub.2DNABT wherein a biztetrazole intermediate is nitrated using a nitrating agent selected from the following: dinitronium disulphate; a mixture of nitric acid and sulfuric acid; a mixture of nitric acid and phosphorous pentoxide; and nitric acid with acetic anhydride.

Methods of preparing propellant compositions for power loads and firearms that include providing pre-shaped particle sized starting material, shaped consistent with a desired final propellant product shape, and thereafter nitrating and stabilizing the pre-shaped starting material using boiling stabilization processes. The resulting nitrated propellants of the methods reliably exhibit complete stabilization, high nitrogen substitution, high shelf life and acceptable ballistic performance.

The present disclosure relates to a continuous extrusion process for producing a celluloid article including several steps and a celluloid article prepared by the continuous extrusion process.
