Type of Ferrocenes on Sensitivities of Ultra-fine AP and Ferrocene Mixture

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.
