High Energy, Lead-Free Ignition Formulation for Thermate.

摘要

An efficient ignition formulation for thermate was developed during the XM89 Enhanced Incendiary Grenade program to use as an alternative to the standard lead oxide-containing formulation used in the AN-Ml4 thermate grenade. This lead-free formulation has provided reliable ignition of the XM89 over a temperature range of -25 degrees F - 120 degrees F when using the M201 Al fuze as the initiator. Reliable ignition of the thermate could also be achieved using 10 g of the new ignition formulation. The AN-Ml4 employs 30 g of ignition mix. The ignition formulation described in this report has also been successfully employed to initiate other pyrotechnic devices such as flares and smoke compositions. It may also have some application as a combination delay/output formulation in devices that do not require either a 'gasless' delay or sealing of the delay tube with reaction products.
