Combustion Performance of a Bi2O3/Al/1Me-3N Mixture Depending on Its Prescription Configuration.

This paper describes a study of combustion performance of a Bi2O3/Al nanothermite mixture with the addition of 1-methyl-3-nitro-1,2,4-triazole (1Me-3N) depending on the content of the latter and the component ratio of a base Bi2O3/Al nanothermite pair. Adding 1Me-3N to the mixture increases the explosive force, but the latter begins to decrease as soon as the additive content reaches over a certain limit. Depending on the prescription configuration, it is possible to increase the explosive force by 22–29% relative to Bi2O3/Al nanothermite. Changing the prescription configuration makes it possible to vary the burning rate of Bi2O3/Al/1Me-3N 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.
