blah, you can find the materials that make thermite in any fire that involves iron and aluminum. Nothing hard about making it.
From the anarchist cookbook about making explosives:
Aluminum powder and rust. Not exactly uncommon in a fire.
From the anarchist cookbook about making explosives:
Thermites are a group of pyrotechnics mixtures in which a reactive metal reduces
oxygen from a metallic oxide. This produces a lot of heat, slag and pure metal. The
most common thermite is ferroaluminum thermite, made from aluminum (reactive metal)
and iron oxide (metal oxide). When it burns it produces aluminum oxide (slag) and
pure iron. Thermite is usually used to cut or weld metal. As an experiment, a 3 lb.
brick of thermite was placed on an aluminum engine block. After the thermite was
done burning, only a small portion of block was melted. However, the block was very
warped out of shape plus there were cracks all through the block.
Ferro-thermite produces about 930 calories per gram The usual proportions of ferro-thermite are
25% aluminum and 75% iron oxide The iron oxide usually used is not rust (Fe2O3) but
iron scale (Fe3O4). Rust will work but you may want to adjust the mixture to about
77% rust. The aluminum is usually coarse powder to help slow down the burning rate.
