摘要：Red phosphorus and potassium nitrate-based compositions exhibit favorable smoke screen formation with high obscuration characteristics at low oxidiser content. The rapid vaporisation of excess red phosphorus at higher flame temperature leads to quick aerodispersion. The obscuration characteristics are due to formation of P2O5 and subsequent reaction with moisture/ humidity in the atmosphere. Obscuration increases with increasing humidity. Extinction coefficient, the shadow cast per unit mass of the composition, is higher in visible and comparatively lower in far infrared.
