Abstract
This paper describes a study of explosive parameters of a Bi2O3/Al nanothermite mixture with the addition of 1-methyl-3-nitro-1,2,4-triazole (1Me-3H) depending on the content of the latter and the component ratio of a Bi2O3/Al basic nanothermite pair. Adding 1Me-3H to the mixture increases the explosive force, but it begins to decrease as soon as the additive content reaches over a certain limit. Depending on the mixture formulation, it is possible to increase the explosive force by 22-29% relative to Bi2O3/Al nanothermite. Changing the mixture composition makes it possible to vary the burning rate of Bi2O3/Al/1Me-3H within a range of 400-690 m/s in charges 2 mm in diameter and within a range of 120-430 m/s in a 0.1-mm thick layer.
