Abstract: The present invention discloses materials, systems and methods for creating metal foams to envelop targets, which involve the formulation of powdered thermite/metal matrices. Essentially, each matrix will include thermite and a foaming agent. Additionally, a thickening agent can be blended into the powdered thermite/metal matrix to create desirable foaming properties when the thermite is ignited. A heat sink agent can also be dispersed throughout the powdered thermite/metal matrix to limit temperature rise in the matrix during a thermite reaction. Further, a binder can be combined with the powdered thermite/metal matrix to hold the formulation together. In use, the formulation is delivered to the vicinity of the target where it is ignited. The resultant metal foam is intended to envelop and neutralize the target.
