A process for the preparation of composite thermite particles, and thermite particles and consolidated objects formed from a plurality of pressed composite particles. The process includes providing one or more metal oxides and one or more complementary metals capable of reducing the metal oxide, and milling the metal oxide and the metal at a temperature below −50° C., such as cryomilling, to form a convoluted lamellar structure. The average layer thickness is generally between 10 nm and 1 μm. The molar proportions of the metal oxide and metal are generally within 30% of being stoichiometric for a thermite reaction.

1. A process for the preparation of composite thermite particles, comprising: providing at least one metal oxide and at least one metal capable of reducing said metal oxide, andmilling said metal oxide and said metal at a temperature below −50° C. to form a convoluted lamellar structure comprising alternating metal oxide layers and metal layers, wherein said metal oxide layers and said metal layers both have an average thickness between 10 nm and 1 μm. 2. The process of claim 1, wherein said temperature is a cryogenic temperature. 3. The process of claim 1, wherein said particles have a dimension between 1 μm and 100 μm. 4. The process of claim 1, wherein said metal oxide layers and said metal layers both have an average thickness of between 10 nm and 0.1 μm, and said particles have a dimension between 0.3 μm and 10 μm. 5. The process of claim 1, further comprising the step of pressing a plurality of said particles to form a consolidated object. 6. The process of claim 5, wherein said pressing is performed a temperature below −50° C. 7. The process of claim 5, further comprising adding a fluidic binder before said pressing. 8. The process of claim 7, wherein said fluidic binder comprises an organic binder. 9. The process of claim 7, wherein said fluidic binder comprises an organic explosive. 10. The process of claim 9, wherein said organic explosive comprises TNT. 11. The process of claim 1, wherein said metal oxide layer comprises at least one selected from the group consisting of CuO, CuO2, Fe2O3, CoO, NiO, MoO3, Fe3O4, WO3, SnO4, Cr2O3 and MnO2. 12. The process of claim 1, wherein said metal layers comprise at least one of the group consisting of Al, Zr, Mg, Be, B and Si. 13. The process of claim 1, wherein said metal layers comprise Al and said metal oxide layers comprise CuO. 14. The process of claim 1, wherein molar proportions of said metal oxide layer and said metal layer is within 30% of being stoichiometric for a thermite reaction. 15. The process of claim 1, wherein said temperature is maintained below said −50° C. for an entire duration of said milling.
