Abstract
Convert infrared tracer compositions are provided. The compositions are formed using peroxide such as strontium peroxide and barium peroxide. Added to these materials is a burn rate catalyst such as boron, iron oxide, cupric oxide, manganese dioxide, carbon, silicon, graphite fibrils, amorphous silica, copper oxide, potassium dodecaborate, the dipotassium salt of bitetrazole amine, and the potassium salt of dilituric acid. The composition also includes alkali metal compounds in order to enhance the infrared emissions. The compositions are bound together using a binder such that the composition results in a granular material having a mean particle size in the range of from about 500.mu. to about 800.mu..
