Abstract

This paper describes the experimental setup for evaluation of pyrotechnic smoke compositions for anti‐laser and anti‐infrared roles using the continuous wave 10.6 μm CO~2~ laser (4 watt) and presents the results for a few pyrotechnic smoke compositions. The particle sizes of the aerosol from pyrotechnic smoke compositions were also determined using Quartz crystal Microbalance ‐ Cascade Impactor. Two smoke compositions containing hexachloroethane, anthracene/naphthalenee, potassium perchlorate and magnesium powder showed more than 97% attenuation of CO~2~ laser, whereas a composition containing zinc oxide, aluminium, iron oxide along with hexachlorocthane was least effective.
