The 30-second video below demonstrates the explosive reaction of a minute quantity of what the chemist calls "homemade super-thermite," composed of "extremely small particle sizes" of a combination of 50 percent ferrocerium, 33 percent copper (II) oxide, and 17 percent sodium nitrate. In this reaction, one-twentieth of a gram (50 milligrams) of the energetic material is ignited. The reaction is both explosive and exothermic, i.e. it releases heat.
This experiment shows that when the components are very small particles and well mixed, the reaction is much faster and more explosive than when larger grain sizes are used. The active thermitic nanocomposite found in the dust of the World Trade Center contained much smaller particles (nano-particles) and was probably much more explosive per gram. The energetic material found in the WTC dust certainly wasn't homemade and it contained aluminum and iron oxide, among other things.
DUST CONTAINED ULTRA-FINE SPHERES OF LEAD
Richard J. Lee did a study of the dust found in the Deutsche Bank building, which was severely damaged during the "WTC Event". Among other things, the Lee study of the WTC dust found large quantities of ultra-fine (i.e. nano-size) spherical particles of lead. These ultra-fine particles of lead are extremely toxic because their small size makes them respirable, and once in the body they are able to penetrate to the nucleus of the human cell. The ultra-fine particles of lead found in the WTC dust were "as much as a million times more respirable than lead in other dust," according to the expert study. This fact is one reason why so many people who were exposed to the dust and smoke from the destroyed towers have succumbed to cancer.
The presence of the ultra-fine spheres of lead in the dust is certainly evidence of extremely high temperatures during the demolition of the towers. They may also be the remains of a novel and highly energetic material that contained a lead oxide. Barium and sulfur are also commonly used in military-grade thermate.
As the Lee study found:
Various metals (most notably iron and lead) were melted during the WTC Event, producing spherical metallic particles… In addition to the spherical iron and aluminosilicate particles, a variety of heavy metal particles including lead, cadmium, vanadium, yttrium, arsenic, bismuth, and barium particles were produced by the pulverizing, melting and/or combustion of the host materials… Many of the materials, such as lead, cadmium, mercury and various organic compounds, vaporized and then condensed during the WTC Event.
The presence of lead oxide on the surface of mineral wool indicate the existence of extremely high temperatures during the collapse which caused metallic lead to volatilize, oxidixe, and finally condense on the surface of the mineral wool… Lead was present as ultra fine spherical particles… The distribution of the lead in the WTC Dust is primarily in the respirable [breathable] fraction… In the Building, lead was found in the ultra fine fraction, and is as much as a million times more respirable than lead in other dust.
MOLYBDENUM SPHERE FOUND IN DUST
The Molybdenum-rich droplet in this micrograph was found in the dust of the pulverized World Trade Center. This spherule was studied by the scientists for the USGS survey of the dust, but it was left it out of the government-funded study, probably because it is evidence of extremely hot temperatures during the demolition of the Twin Towers. Such high temperatures cannot be explained by the version of events provided by the government. In reality, this droplet was probably formed in an exothermic reaction of ultra-fine particles of aluminum with molybdenum trioxide. This is one of the most energetic (hot, explosive) forms of thermite. (Source - "Extremely High Temperatures during the WTC Destruction," Steven E. Jones, et al)
The melting temperature of molybdenum is 4,753 degrees F, or 2,623 degrees C. There is no explanation how molten molybdenum was created during the destruction of the Twin Towers if it was not caused by an extremely intense thermitic reaction involving molybdenum trioxide.
The following video is a simple demonstration of the explosive energy of the aluminothermic reaction of aluminum with cupric oxide (copper). This explosive reaction was done using a small amount of the components in fine granular sizes. If these components had been combined using ultra-fine (nano-size) particles the reaction would have been much more explosive. Other metal oxides react even more violently.
