Impact sensitivity, friction sensitivity and thermal decomposition tests were applied to study the influence of different ferrocene derivatives on the sensitivities of ultra-fine AP/ferrocene mixtures. Experimental results showed that the ferrocenederivatives in this paper increase the impact and friction sensitivities of the ultra-fine AP/ferroceen mixtures. The impact sensitivities of the ultra-fine AP/ferrocene mixtures are not related to the Fe contents of ferrocene catalyst. However, the friction sensitivities of the ultra-fine AP/ferrocen mixtures are positively related to the Fe content of ferrocene catalyst. Some kinds of ferrocene catalysts, such as, SH-F-1, SH-F-2, SH-F-3, GFP and SH-F-5, present a new exothermic peak in DSC curve of ultra-fine AP/ferrocene mixture, show the greater thermal sensitivities.
