Condensed phase energetic time delay compositions

摘要

An environmentally safe, nontoxic energetic time delay composition useful in small diameter aluminum tubes (i.e., typical military delay housings), which provides desired delay propagation rates of from less than about 2 to about 38 mm/s through such delay housings—the compositions being compressed stoichiometric mixes of Ti and C powders; Ni and Al powders; a combination of Ti/C and 3Ni/Al powders; and a combination of Ti/C and Ni/Al powders, diluted with inert alumina.

1. An energetic time delay fuse composition useful in typical military delay tube housings, which composition comprising, a mixture of about 35 to about 40 wt. % of a stoichiometric mix of Ti and C, with about 65 wt. % to 60 wt. % of a stoichiometric mix of 3Ni and Al wherein said compressed mixture of powders reacts at a propagation rate of from less than about 2 mm/s to about 38 mm/s;
wherein said compressed mixture of powders reacts in a condensed phase generating less than 10 ml/g of gas; wherein said compressed mixture of powders reacts in an exothermic manner at a reaction temperature of over 1800 K; and whereby said reaction propagates the entire length of the delay tube housing.
