Masking material and use of the material to mask a target and ammunition for disseminating such masking material
Disclosed is a masking material intended to be disseminated by an ammunition or a launcher to create a cloud that masks a target with respect to electromagnetic radiation in a given wavelengths range. This material contains at least one aluminium oxyhydroxide, such as boehmite or pseudoboehmite. Also disclosed is an ammunition enabling the dissemination of such masking material and the use of aluminium oxyhydroxide, such as boehmite or pseudoboehmite as a masking material that can be disseminated by an ammunition.

USE OF A HALOGENATED SALT OF TETRAPHENYLPHOSPHONIUM AS A SMOKE-PRODUCING AGENT AND SMOKE-PRODUCING PYROTECHNIC COMPOSITION INCORPORATING SUCH MATERIAL
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.

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.
