Abstract
A non-self-passivating fuel such as boron or magnesium is protected from exposure to oxygen sources by a self-passivating fuel layer such as aluminum or titanium. When the non-self-passivating fuel is utilized within a layered structure of alternating fuel and oxygen source layers, self-passivating fuel layers located between each non-self-passivating fuel layer and each oxygen source layer. The self-passivating fuel oxidizes until self-passivation is reached, protecting the non-self-passivating fuel from oxidation. Any of the non-self-passivating fuel which does not oxidize is available for use as fuel in any fuel-oxygen source reaction.
Claims11
A fuel, comprising:
- a non-self-passivating metal fuel;
- an oxygen source;
- and
- a self-passivating metal fuel disposed between the non-self-passivating metal fuel and the oxygen source;
- whereby the self-passivating fuel oxidizes by reacting with the oxygen source to form a passivation layer, the passivation layer resisting oxidation of the non-self-passivating fuel from the oxygen source until the fuel is ignited.
