@Baldimo,
General information is always helpful, I agree.
What is really important though, is,
What was a US developed, at Lawrence Livermore Laboratory, recently discovered and patented, circa 1996/97, non-commercially available, military much higher grade than thermite explosive doing at the WTC?

This was most probably accomplished through the use of nano-thermites, which are hightech
energetic materials made by mixing ultra fine grain (UFG) aluminum and UFG
metal oxides; usually iron oxide, molybdenum oxide or copper oxide, although other
compounds can be used (Prakash 2005, Rai 2005). The mixing is accomplished by
adding these reactants to a liquid solution where they form what are called “sols”, and
then adding a gelling agent that captures these tiny reactive combinations in their
intimately mixed state (LLNL 2000). The resulting “sol-gel” is then dried to form a
porous reactive material that can be ignited in a number of ways.
The high surface area of the reactants within energetic sol-gels allows for the far higher
rate of energy release than is seen in “macro” thermite mixtures, making nano-thermites
“high explosives” as well as pyrotechnic materials (Tillitson et al 1999). Sol-gel nanothermites,
are often called energetic nanocomposites, metastable intermolecular
composites (MICs) or superthermite (COEM 2004, Son et al 2007), and silica is often
used to create the porous, structural framework (Clapsaddle et al 2004, Zhao et al 2004).
Nano-thermites have also been made with RDX (Pivkina et al 2004), and with
thermoplastic elastomers (Diaz et al 2003). But it is important to remember that, despite
the name, nano-thermites pack a much bigger punch than typical thermite materials.

============
Other than US government, military scientists and their hookups, scientists don't even know how to make this superthermite/nanothermite.
