A method of manufacturing a pyrotechnic time delay composition includes admixing together a solid oxidizer, a solid fuel and water to form an aqueous slurry. The slurry is transformed into droplets. The droplets are gas-dried to form particles comprising the oxidizer and the fuel, with the particles thus constituting a pyrotechnic delay composition.
1. A method of manufacturing a slow-burning pyrotechnic time delay composition, wherein the method includes: admixing together, under high shear and in the absence of a sensitizing oxidizer, a solid oxidizer, a solid fuel and water to form an aqueous slurry;transforming the slurry into droplets; andgas-drying the droplets to form particles comprising the solid oxidizer and the fuel, with the particles thus constituting the pyrotechnic delay composition. 2. The method according to claim 1, wherein a surfactant is present during the admixing of the oxidize...
