Abstract:
1. A process for producing an aluminum fuel in which the aluminum is capable of reacting with an oxidizer to form a passivating oxide, comprising: (a) providing a passivation preventing agent in liquid phase; (b) combining aluminum in solid phase with the passivation preventing agent in a mixture having an initial weight percentage of passivation preventing agent to aluminum; (c) maintaining the mixture at a temperature equal to the equilibrium point temperature corresponding to a desired weight percentage of the passivation preventing agent on the equilibrium line between solid phase aluminum and solid phase aluminum+liquid passivation preventing agent, for a time sufficient for the liquid passivation preventing agent to reach saturation of the aluminum; and (d) cooling the mixture at a controlled cooling rate to achieve a solid-like mixture at about the desired weight percentage of the passivation preventing agent that is largely free of macroscopic liquid phase of the passivation preventing agent.
