Preparing solid energetic compositions from coated particles and liquid oxidizers

摘要

Solid energetic compositions are prepared from powdered solid components such as metallic aluminum fuel and liquid oxidizers by forming a coating of polyvinyl alcohol over the powdered solid by precipitation from a solution of polyvinyl acetate, and combining the coated particles with liquid oxidizer which will permeate and swell the particle coating, causing the particles to agglomerate into a solid rubbery mass.
