Abstract

The invention relates to the use of at least one halogenated salt of tetraphenylphosphonium as a smoke-producing agent in a pyrotechnic composition intended to provide masking of an objective with respect to electromagnetic radiation in a given wavelength range. The invention also relates to a smoke-producing pyrotechnic composition comprising at least one halogenated salt of tetraphenylphosphonium.

Abstract

One subject of the invention is a masking material which is intended to be dispersed by ammunition or a launcher in order to produce a cloud that ensures the masking of a target with respect to electromagnetic radiation in a given range of wavelengths. This material is characterized in that it comprises at least one aluminium oxyhydroxide, such as boehmite or pseudo-boehmite. Another subject of the invention is ammunition for dispersing such a masking material and the use of aluminium oxyhydroxide, such as boehmite or pseudo-boehmite, as masking material that can be dispersed by ammunition.
