The explosive nature of nanothermite

"In the last few years, a series of peer-reviewed scientific articles has been published that establish the presence of thermitic materials at the World Trade Center (WTC). [A-D]

Although we know that nanothermite has been found in the WTC dust, we do not know what purpose it served in the deceptive demolition of the WTC buildings. It could be that the nanothermite was used simply to drive fires in the impact zones and elevator areas – fires which would otherwise have gone out too early or not been present at all – and thereby create the deception that jet fuel-induced fires could wreak the havoc seen. Nanothermite might also have been used to produce the explosions necessary to destroy the structural integrity of the buildings.

Nanothermite, also called superthermite, is the common name for a subset of metastable intermolecular composites (MICs) characterized by a highly exothermic reaction after ignition. Nanothermites contain an oxidizer and a reducing agent that are intimately mixed on the nanometer scale. Such nano-energetics are produced for various applications including propellants, explosives, and pyrotechnics.

There are various ways to make nanothermites. They can be made as solid mixtures of aluminum and metal oxides which are typically produced using techniques like dynamic vapor phase condensation and arrested reactive milling. These mixtures are much like typical thermite mixtures, but with the components introduced on a much smaller scale. Alternatively, nanothermites can be made in a liquid solution that later gels, capturing the reactive components in an intimately mixed composite which is dried before it can be ignited. These are called sol-gel nanothermites, also known more generally as energetic nanocomposites..."
