Abstract
A transmission attenuating aerosol, which is transmission attenuating and has a low refractive index for electromagnetic radiation, particularly for absorption within the IR-range, which aerosol includes activated carbon having approximately 80% of the particles distributed within a range of diameters between 1 and 9 .mu.m and 10% above and below these limits, the activated carbon also being arranged having high mechanical strength.
Claims7
An aerosol composition for attenuating the transmission and reflectance of electromagnetic radiation within the infrared range consisting essentially of activated carbon particles, 80% of said particles having diameters which are approximately equally distributed in the range between 1 to 9 .mu.m and approximately equal amounts of the remaining activated carbon particles having diameters larger and smaller than said range.
