A thermobaric self-sustaining reactive composition, method and device for defeating chemical or biological agents includes a first material including at least one of a Group IV or Group V metal; a second material reactive with the first material in an exothermic intermetallic reaction to generate heat sufficient to vaporize a third material; and the third material that when vaporized combusts with air producing an elevated temperature sufficient to destroy the chemical and biological agents. The device includes a container having a center core explosive driver with the self-sustaining reactive composition surrounding the center core explosive driver.

1. A thermobaric self-sustaining reactive composition for defeating chemical or biological agents comprising: a first material comprising at least one of a Group IV or Group V metal;a second material reactive with said first material in an exothermic intermetallic reaction to generate heat sufficient to vaporize a third material;said third material, which, when vaporized, combusts with air producing an elevated temperature sufficient to render ineffective said chemical or biological agents,wherein said composition is capable of producing said elevated temperature in the absence of an oxidizer as a component of the composition. 2. The composition of claim 1 wherein said first material is titanium. 3. The composition of claim 1 wherein said first material is present in an amount of from about 15-75% by mass. 4. The composition of claim 1 wherein said second material is selected from the group consisting of aluminum, boron, carbon, nitrogen, silicon and combinations thereof. 5. The composition of claim 1 wherein said second material is present in an amount of about 5-40% by mass. 6. The composition of claim 1 wherein said third material is present in an amount of about 5-80% by mass. 7. The composition of claim 1 further comprising wax. 8. The composition of claim 1 wherein said wax is polychlorotrifluoroethylene wax. 9. The composition of claim 1 wherein said composition comprises about 40-60% by mass of titanium powder, about 15-30% by mass of boron powder, about 10-20% by mass of aluminum-magnesium alloy powder, about 5-15% by mass of polytetrafluoroethylene powder and about 2.5-7.5% by mass of polychlorotrifluoroethylene wax. 10. The composition of claim 1 wherein said composition comprises about 20-35% by mass of titanium powder, about 7.5-15% by mass of boron powder and about 40-80% by mass of red phosphorus powder. 11. The composition of claim 1 wherein said composition comprises about 18-36% by mass of titanium powder, about 7.5-12.5% by mass of boron powder, about 4.5-9.5% by mass of aluminum-magnesium alloy powder and about 45-75% by mass of polychlorotrifluoroethylene wax. 12. The composition of claim 9 comprising about 48.22% by mass of titanium powder, about 21.78% by mass of boron powder, about 15% by mass of aluminum-magnesium alloy powder, about 10% by mass of polytetrafluoroethylene powder and about 5% by mass of polychlorotrifluoroethylene wax. 13. The composition of claim 10 comprising about 27.55% by mass of titanium powder, about 12.44% by mass of boron powder and about 60% by mass of red phosphorus powder. 14. The composition of claim 11 comprising about 22.90% by mass of titanium powder, about 9.96% by mass of boron powder, about 7.12% by mass of aluminum-magnesium alloy powder and 60% by mass of polychlorotrifluoroethylene wax. 15. A thermobaric device for defeating chemical or biological agents comprising: a container having a center core explosive driver and a self-sustaining reactive composition for defeating said agents surrounding said center core explosive driver;wherein said self-sustaining reactive composition comprises:a first material comprising at least one of a Group IV or Group V metal;a second material reactive with said first material in an exothermic intermetallic reaction to generate heat sufficient to vaporize a third material; andsaid third material, which, when vaporized, combusts with air producing an elevated temperature sufficient to render ineffective said chemical or biological agents,wherein said composition is capable of producing said elevated temperature in the absence of an oxidizer as a component of the composition. 16. The thermobaric device of claim 15 wherein said first material is a titanium. 17. The thermobaric device claim 15 wherein said second material is selected from the group consisting of aluminum, boron, carbon, nitrogen, silicon and combinations thereof. 18. The thermobaric device of claim 15 wherein said container is configured to be delivered by airdrop or land carrier. 19. The composition of claim 1, wherein said composition is absent an oxidizer. 20. The thermobaric device of claim 15, wherein said composition is absent an oxidizer. 21. A thermobaric self-sustaining reactive composition for defeating chemical or biological agents consisting of: a first material comprising at least one of a Group IV or Group V metal;a second material reactive with said first material in an exothermic intermetallic reaction to generate heat sufficient to vaporize a third material;said third material, which, when vaporized, combusts with air producing an elevated temperature sufficient to render ineffective said chemical or biological agents; andoptionally at least one additive such as wax,wherein said composition is absent an oxidizer.
