An exothermic metallic composition for a body warmer comprising (1) one or more members selected from the group comprising iron, aluminum and magnesium in the form of fine particle and (2) an oxidation agent comprising one or more members selected from the group comprising ferrosoferric oxide, plumboblumbic oxide, trimanganese tetroxide, black copper oxide and manganese dioxide in the form of fine particle, water and particulate oxidation assistants such as sodium chloride and active carbon.

Exothermic metallic composition

Positive rocket motor pressure hull venting in the case of deck fires is vided by placement of thermite masses at spaced locations on the interior of the hull. Small cylindrical masses as well as strip formed masses are employed. The thermite mass includes a small amount of structurally formed aluminum as well as the conventional powdered aluminum.

Pressure vessel penetrator

A stacked load of gas-forming pyrotechnic fuel pellets comprising metal, metal oxide and PTFE in varying amounts for use in apparatus for severing conduits in high pressure environments.

Pyrotechnic compositions for severing conduits

A thermite mixture with a low autoignition temperature for venting ordnancease sidewalls during fuel fire, having increased density, tensile strength and elasticity.

Bonding agents for thermite compositions

Metallothermisches Reaktionsgemisch, welches aus einem Metalloxid, einem gegenuber dem Metalloxid unedleren Metall und gegebenenfalls weiteren Zuschlagsstoffen besteht, wobei die einzelnen Bestandteile in Form kleiner Teilchen vorliegen, wobei mindestens 20 Gew.-% des Metalloxides in Form kugelformiger oder zumindest angenahert kugelformiger Partikel einer Teilchengrose von > 0 bis 3,0 mm vorliegen. A metallothermic reaction mixture, which consists of a metal oxide, a compared to the metal less noble metal and optionally other additives, where the individual components are present in the form of small particles, where at least 20 wt .-% of the metal oxide in the form of spherical or at least approximately spherical particles of a particle size of present> 0 to 3.0 mm. Durch die erfindungsgemase Zusammensetzung des Reaktionsgemisches wird eine Verstetigung und Vergleichmasigung der Reaktion erreicht. The inventive composition of the reaction mixture a stabilization and homogenization of the reaction is reached.

Metallothermic reaction mixture

THIS INVENTION RELATES TO AN ALUMINOTHERMIC REACTION MIXTURE CONSISTING ESSENTIALLY OF ALUMINUM AND IRON OXIDE AND CONTAINING ABOUT 0.1 TO 5 PERCENT BY WEIGHT, BASED ON THE TOTAL WEIGHT OF THE MIXTURE, OF AT LEAST ONE ALUMINOTHERMICALLY REDUCIBLE OXIDE HAVING A PARTICLE SIZE IN THE RANGE OF ABOUT 0.05 TO 50U.
