[What, you don't know that thermite is basically aluminum and rust?
Mr. SFC Ollie:
Scientist and Physicists know quite a bit about the characteristics of thermite. Your simple "aluminum and rust" (in mixed power form) is used to weld steel rails together. Here is what Wikipedia says about the "aluminum and rust" reaction ... and it not just some "little-bit-of-rust-on-this-pipe-here-and-an-alumimun-beer-can-over-there" proximity that creates this highly exothermic reaction.
"From Wikipedia:
Thermite is a pyrotechnic composition of a metal powder and a metal oxide, which produces an exothermic oxidation-reduction reaction known as a thermite reaction. If aluminum is the reducing agent it is called an aluminothermic reaction. Most varieties are not explosive, but can create short bursts of extremely high temperatures focused on a very small area for a short period of time.
Thermites can be a diverse class of compositions. The fuels are often aluminium, magnesium, calcium, titanium, zinc, silicon, and boron. The oxidizers can be boron(III) oxide, silicon(IV) oxide, chromium(III) oxide, manganese(IV) oxide, iron(III) oxide, iron(II,III) oxide, copper(II) oxide, and lead(II,III,IV) oxide.
The most common thermite is aluminium-iron(III) oxide.
Reaction
The aluminium reduces the oxide of another metal, most commonly iron oxide, because aluminium is highly reactive:
Fe2O3 + 2Al → 2Fe + Al2O3 + heat
The products are aluminium oxide, free elemental iron,[2] and a large amount of heat. The reactants are commonly powdered and mixed with a binder to keep the material solid and prevent separation."
So are you dismissive of the ability of Thermite to weaken and cut steel beams?
