PCT No. PCT/FR91/00920 Sec. 371 Date Jul. 1, 1992 Sec. 102(e) Date Jul. 1, 1992 PCT Filed Nov. 21, 1991 PCT Pub. No. WO92/09544 PCT Pub. Date Jun. 11, 1992.The technical field of the invention is concerned with smoke-generating devices and with powdered materials scattered by dispersion means in order to produce a camouflaging cloud which is effective in the infrared region. The material in accordance with the invention essentially consists of at least one powder having grains provided with a coating which is chemically inert with respect to the grain, which affords resistance to temperatures lower than or equal to the dispersion temperature, and which does not oxidize in free air.
