Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The development of a red, chlorine‐free pyrotechnic illuminant of high luminosity and spectral purity was investigated. Red‐light emission based solely on transient SrOH_(g) has been achieved by using either 5‐amino‐1<italic>H</italic>‐tetrazole or hexamine to deoxidize the combustion flame of a Mg/Sr(NO₃)₂/Epon‐binder composition and reduce the amount of both condensed and gaseous SrO, which emits undesirable orange‐red light. The new formulations were found to possess high thermal onset temperatures. Avoiding chlorine in these formulations eliminates the risk of the formation of PCBs, PCDDs, and PCDFs. This finding, hence, will have a great impact on both military pyrotechnics and commercial firework sectors.</p> </abstract>
