Co‐precipitation of lead azide with various tetrazole and nitrophenol derivatives is discussed. Thermal behaviour of lead azide before and after co‐precipitation is studied suing DSC. Thermal study indicated that the co‐precipitation of lead azide with other flame sensitive compounds produced an intimate mixture of lead azide and lead salts of tetrazole and nitrophenyl derivatives but not a single compounds. Explosive properties evaluation indicated that the co‐precipitation process not only improves the flame sensitivity of lead azide but also eliminates the hazardous process of physical mixing of lead azide with flame sensitive materials. A good correlation between thermal sensitivity and flame sensitivity is noticed. Both thermal and flame sensitivity decreases.
