Upon igniting Thermite, the mixture produces an extremely exothermic reaction, which has been measured at around 2500 degrees Celsius (or about half as hot as the surface of the sun).

The polymer produces a gas when the thermite reaction occurs, the gas slowing the thermite reaction.

Said invention can be used, for example for aluminothermic welding, in particular in a tunnel or underground.

The invention concerns a mold for aluminothermal welding of railway tracks.

The conversion is carried out on-site using an aluminothermic reaction.

The mixture reacts completely and in a self-propagating manner, as in a thermite reaction, after the mixture has been ignited by a heating coil.

The coarse powder is used in aluminothermics (thermite reaction).

A power source for actuating a subsurface tool is described herein, the power source comprising thermite in a quantity sufficient to generate a thermite reaction, and a polymer disposed in association with the thermite.

The red portion of these chips is found to be an unreacted thermitic material and highly energetic.

The aluminium-zirconium master alloy is produced by aluminothermic reduction of zirconium from compounds thereof in a molten metal halide medium.

Upon igniting Thermite, the mixture produces an extremely exothermic reaction, which has been measured at around 2500 degrees Celsius (or about half as hot as the surface of the sun).

The invention relates to a cover (3) for closing an upper aperture (17) of the reaction chamber (15) of the crucible (2).

The red portion of these chips is found to be an unreacted thermitic material and highly energetic.

The company Delachaux SA is a producer of pure chrome metal by aluminothermic process.

Its basis was the aluminothermic procedure patented in 1895 by Professor Hans Goldschmidt.
