  • Publication number: 20110308420
    Abstract: In accordance with aspects of the invention, an infrared signature powder (“IR powder”) suitable for marking targets and other objects is provided. The IR powder primarily includes porous, pyrophoric iron and moderators. The duration, temperature, and intensity of the emitted infrared radiation can be tailored during the powder's production process by adjusting the proportion or properties of the moderators in the IR powder. Additionally, a method of producing the IR powder is provided. The method can include the following general steps: heat a blend of aluminum and iron powders to cause an inter-metallic reaction; leach the aluminum from the iron; and mix a selected moderator and a binder with the iron in selected proportions to create the IR powder. Many of these steps are performed in an oxygen-free environment to prevent the iron from prematurely oxidizing. Similarly, the IR powder is encapsulated in an oxygen-free frangible ampoule or other container.
