Functionally coated non-oxidized particles and methods for making the same

摘要

Air-stable coated particles which include an oxidizable core having an organic ligand coating substantially encompassing the oxidizable core, are disclosed and described. The coated particles can also be substantially free of an oxide layer, especially oxide layers around the oxidizable core. As such, the organic ligand coating acts as a protective or passivating coating. The air-stable coated particles can be formed via a particle size-reduction process. An oxidizable particulate can be crushed and contacted with an organic ligand. The process conditions are maintained such that an oxide layer is preempted from forming on the oxidizable core. Such materials can be effective as high energy density additives for various fuels, pyrotechnic, ionic liquids, and rocket propellant applications and for biomedical applications.
