The spectral performance, sensitiveness to ignition stimuli and burning rate of bi ‐spectral flare formulations based on tetrazole containing fuels, 5‐phenyl‐1 H ‐tetrazole, 5,5′‐(1,4‐phenylene)bis(1 H ‐tetrazole) and 5‐(4‐nitro‐phenyl)‐1 H ‐tetrazole, utilizing potassium perchlorate as the oxidizer, are reported. The formulation based on 5‐(4‐nitro‐phenyl)‐1 H ‐tetrazole yielded the highest spectral efficiency in the β ‐band (44.1 J g −1 sr −1 ). The formulation based on 5‐phenyl‐1 H ‐tetrazole gave the highest color ratio ( θ β/α =6.8) and was the least sensitive.
