Scientific Evidence that the world trade centre was demolished using explosives and or incendiaries.Iron microspheres.Iron rich microspheres found in the wtc dust by RJ LEE and Stephen Jones indicate extremely high temperatures , high enough to melt steel in order to form iron spheres. Iron spheres have chemical signature of thermate/thermite.Debunkers argument1.Iron spheres came from building construction ,oxyacetylene torch. The RJ Lee report also provides a micrograph and XEDS data for iron-rich spheres observed in the WTC dust; for example, their figure 21 (below, left) shows an “SEM image and EDS of spherical iron particle [1].” We likewise observe high-iron, relatively low oxygen spheres (e.g., below right and Fig. 4), which we find are unlike spheres gathered from cutting structural steel with an oxyacetylene torch. 2.Flyash,dust, Paint plus rust. Old buildings. Friction etc other causes.. Moreover, the RJ Lee report provides provocative data regarding the abundance of observed iron-rich spheres. A WTC dust sample acquired at 130 Liberty Street shows a “mean of composition” of “Fe spheres” of 5.87% which is very high compared with “Fe spheres” found in ordinary building dust of only 0.04% [1]. As the report notes, the WTC dust has unusual identifying characteristics – in particular, the WTC Extremely high temperatures during the WTC destructiondust in this sample has nearly 150 times (5.87/0.04) the amount of iron-rich spheres as ordinary dust(where Fe spheres can arise from micrometeorites, for example). “Various metals (most notably iron and lead) were melted during the WTC Event, producing spherical metallic particles. Exposure of phases to high heat results in the formation of spherical particles due to surface tension...” 'These types of particles are classic examples of high temperature or combustion by-products and are generally absent in typical office dust...” “Particles of materials that had been modified by exposure to high temperature, such as spherical particles of iron and silicates, are common in WTC Dust because of the fire that accompanied the WTC Event, but are not common in “normal” interior office dust...” Evidence of Extremely high Temperatures Official explanation of temperatures found at wtc . Finally, we consider the temperatures reached in normal building fires, jet-fuel fires and in the World Trade Center buildings. Maximum temperatures due to fires in the WTC of around 1,000 C are argued by Thomas Eagar: All of these estimates for the WTC fires (including burning jet fuel) put the temperature well below the melting point of steel, about 1,500 °C [17]. In fact, the non-melting of WTC steel is emphasized by NIST – but they fail to address the presence of large numbers of iron-rich spherules in the dust published in USGS and other reports before the NIST study was published in October 2006 [16, 18]. Whats wrong with this NIST fails to explain evidence of extremely high temperatures found in the WTC dust. We agree with the RJ Lee report that the abundance of “spherical particles of iron and silicates” is proof of high temperatures, and that these particles are not common in normal office dust, but we do not agree that this abundance is necessarily due to the “fire that accompanied the WTC Event”. Before drawing such a conclusion, one must scrutinize the temperatures and other conditions needed to form these molten spheres (iron melts at 1,538 °C (2,800 °F) while iron (III) oxide melts at 1,565 °C (2,849 °F) [6] and aluminosilicates melt around 1,450 C [7]) and then compare with conditions reached in the WTC fires. We will turn to this task, after considering other data which also point to anomalously high temperatures during the WTC destruction. 4.2. Volatilized lead The RJ Lee report notes “extremely high temperatures during the collapse which caused metallic lead to volatilize, oxidize, and finally condense on the surface of the mineral wool [1].” Again, “metals were vaporized at the WTC during the WTC Event and either deposited on WTC Dust or deposited directly onto surfaces in the Building [1].” Where do the requisite high temperatures come from? The temperature required to volatilize/boil lead is 1,740 C or 3,164 F [8]. No explanation for the origin of the indicated “extremely high temperatures during the collapse” is offered in the RJ Lee report. 4.3. Molybdenum spherule in the USGS data set Mo melts at 2,623 °C (4,753 °F) [10], although addition of other elements may lower the melting point. No explanation of the high temperature needed to form the observed Mo-rich spherule is given in the USGS material (either published or obtained by FOIA action). 4.4. Materials from WTC with a “Swiss-cheese appearance” corroborate high temperatures Dust particles from the WTC collapse show a “Swiss cheese appearance as a result of boiling and evaporation,” as reported in the RJ Lee report: The severe corrosion and subsequent erosion of Samples 1 [WTC7] and 2 [Towers] are a very unusual event. No clear explanation for the source of the sulfur has been identified [13]. It is interesting that the FEMA report discussed the “evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation” and called for further investigation, [13] – but the subsequent NIST report [15] failed to address this evidence. Nor did NIST address the published observations of abundant iron-rich spherules in the WTC dust [1, 2]. We find that these effects are important to understanding the events of 9/11/2001 and should not be neglected. 4.5. Summary of Temperatures Required by the WTC Data The formation of spherules in the dust implies the generation of materials somehow sprayed into the air so that surface tension draws the molten droplets into near-spherical shapes. That shape is retained as the droplet solidifies in the air. Spherules observed in the WTC dust include iron-rich, molybdenum-rich and silicate varieties. The temperatures required to melt iron, silicates, and molybdenum, and to vaporize lead and aluminosilicates (as discussed above) are summarized in table 1. To form Fe-O-S eutectic (with ~50 Mol % sulfur) in steel 1000Celcius To melt aluminosilicates (spherule formation) 1450C To melt iron (spherule formation) 1538c To melt iron (III) oxide (spherule formation) To vaporize lead 1740C To melt molybdenum (spherule formation) To vaporize aluminosilicates 2623C Molten steel Video of molten steel flowing from south tower , eyewitness reports of flowing molten steel , FEMA report on corroded steel column melted steel .What the debunkers say The molten material was aluminium from the plane. Molten aluminium cannot turn yellow or orange as according to NIST office furniture melted together with aluminium to cause a yellow orange color.. In experiments as expected any office furniture added to molten aluminium burns off and doesnt melt with aluminium to create an orange color... Noone has been able to replicate this magical theory of aluminium melting with other 'stuff' to create an orange color.What the yellow orange color means The molten material was above the melting point of steel which has a yellow orange hot color .Nanothermite/thermiteDebunkers such as national geo claim that thermite with their experiment is not powerful enough to melt through steel, another experiement actually proved them wrong http://www.youtube.com...Not to mention nanothermite was also used which is more powerful than thermite http://911research.wtc7.net...NANOTHERMITE http://www.benthamscience.com... nanothermite found in wtc dust, partially reacted nanothermite forming iron spheres prove a thermitic reaction. calorimter prove an explosvie reaction, elemental aluminium at nano scale prove high energy reactants in wtc dust.
