摘要：

The transmission rate and mass concentration of nano-carbon black were measured in 20 m(3) smoke screen chambers. Consequently, the mass extinction coefficients of nano-carbon black to 8-12 mu m and 1.06 mu m were calculated. The experimental results showed that the mass extinction coefficient to 8 -12 mu m of the new-type materials of nano-carbon black was 1.5 m(2).g(-1), and was similar to the superiority smoke agent of copper powder. The mass extinction coefficient to 1.04 mu m was 2.17 m(2).g(-1). Its extinction effect was far better than that of nano-graphite, and was similar to that of nano-Ag powder and other precious metal materials. But nano-carbon black has higher performance-price ratio. It can be used as interference material of large area smoke on the premise. So it has greater application potential.
