The growing reservations against the use of any kind of chlorine source in pyrotechnic items revolutionize the predominantly empirical development of strobe formulations in two ways. First, a conventionally applied ammonium perchlorate oxidizer needs to be replaced. Second, visible light emissions should no longer be generated by metastable monochloride species. Moreover, until now, toxic substances such as potassium dichromate have been added in order to achieve a more pronounced strobe effect. This work evaluates the potential of stearic acid-treated ceric ammonium nitrate to serve as an oxidizing agent in next-generation strobe compositions. For this purpose, its microscopic structure, energetic properties, and stability under ambient conditions were assessed. A two-component mixture with a magnesium–aluminum alloy was investigated, which should allow for the introduction of copper-based colorants. This potentially paves the way for the first environmentally friendly blue strobe formulations.

一种稳定的硝酸铈铵氧化剂在环保烟火频闪灯中的显微研究及应用
越来越多的人反对在烟火制品中使用任何种类的氯源，从而以两种方式彻底改变了频闪配方的主要经验发展。首先，需要更换传统应用的高氯酸铵氧化剂。其次，亚稳态一氯化物不应再产生可见光发射。而且，直到现在，为了达到更明显的频闪效果，还添加了重铬酸钾等有毒物质。这项工作评估了硬脂酸处理的硝酸铈铵在下一代频闪灯组合物中用作氧化剂的潜力。为此，对其微观结构、能量特性和环境条件下的稳定性进行了评估。研究了镁铝合金的双组分混合物，这应该允许引入铜基着色剂。这可能为首个环保蓝色频闪灯配方铺平道路。
