Abstract
The invention pertains to a smoke-producing pyrotechnical composition which is designed for the production of a smoke screen that prohibits the transmission of infrared radiance from a target to a pick-up. It includes a compound which generates, through thermal decomposing, carbon particles of which the size is included between about 1 and 14 .mu.m, and an oxidoreducing system which reacts at a temperature that exceeds 1000 degrees C. and a binding agent. The compound which generates carbon particles can be hexachloroethane, hexachlorobenzene, naphtalene, anthracene, or their mixture; the reducing agent can be a metal powder (magnesium) and the oxidizer hexachlorobenzene and/or hexachloroethane. An application to the execution of smoke-producing devices.
