A composition of matter for an incendiary device includes a thermate component consisting of strontium nitrate Gr A, black iron oxide Gr B, aluminum Gr D Cl 5, aluminum Gr E Cl 6, sulfur Gr E, and polyacrylic rubber; and an ignition component consisting of potassium nitrate, titanium, aluminum, silicon, sulfur, charcoal, and polyacrylic rubber, wherein the thermate component consists of a barium nitrate free thermate formulation, and wherein the ignition component consists of a lead free ignition formulation. A parts by weight composition of the thermate component consists of 20.59% strontium nitrate Gr A, 48.04% black iron oxide Gr B, 17.57% aluminum Gr D Cl 5, 9.88% aluminum Gr E Cl 6, 1.96% sulfur Gr E, and 1.96% polyacrylic rubber, and a parts by weight composition of the ignition component consists of 66% potassium nitrate, 11% titanium, 8% aluminum, 6% silicon, 2% sulfur, 5% charcoal, and 2% polyacrylic rubber. Preferably, the first and second components are consolidated together using a ram having a sharp-edged profile.

Composition of matter for an incendiary device and method of manufacture

The various embodiments provide an incendiary device utilizing a multiple hollow core-burner technique that facilitates producing large diameter cuts through steel targets. To facilitate this result, the various embodiments incorporate a multiple-core burning design with multiple orifices at the base for directing multiple jets of molten reaction product at the target. The various embodiments further incorporate an optional holding device as a means for locking the device onto a target. Devices in accordance with the invention having a base diameter of 2.312&Prime; have been shown to be capable of producing an approximately 2&Prime; diameter hole through &frac14; inch thick steel plate using a 275 g thermite charge within a container three-quarters the size of a standard AN-M14 Thermite Grenade package.

Incendiary device

A holding device for a pyrotechnic, incendiary device. More particularly, a holding device for a thermite or thermate based destructive device or enhanced incendiary grenade. The device assembly allows for firm attachment of pyrotechnic, incendiary devices, particularly enhanced incendiary grenades, to targets having various surface shapes and orientations, or formed of various materials. The holding device is inexpensive and easily reproducible.

Pyrotechnic incendiary grenade holding device

Pyrotechnic burster composition combines high explosive energy when confined, with reduced ignition hazard when unconfined. The composition includes pyrotechnic mixtures of KClO , metal powders, and pentaerythritol or terephthalic acid.

Pyrotechnic burster composition

A mixture containing 3,3-bis(aziodomethyloxetane) and terephthalic acid for se as a white cloud producing composition which may be used by the military for screening field operations.

Composition

This invention relates to a smoke-producing composition containing a dye 1,4,- benzenedicarboxylic acid. The acid is useful for purging slag and solid clinker while lowering the steady state burning temperature of the composition. The coloring agent used by the composition does not degrade. The acid is an efficient coolant for the composition and takes advantage of sublimation reactions to produce the properties enumerated here.

Colored smoke-producing composition

The present invention is an essentially non-toxic, smoke-producing, pyrotnic composition. The composition uses 1,4 benzenedicarboxylic acid which produces a superior visual screening smoke when vaporized by heat provided a reaction between suitable fuel and oxidizer. The composition additionally contains potassium chlorate and sugar. The composition burns at a low temperature without a visual flame and is suited for use in smoke grenades and smoke pots.
