Still unexplained: eutectic erosion of steel, iron spherules, molybdenum spherules, vaporized lead. [View All]

It's not just http://www.tms.org/pubs/journals/JOM/0112/Biederman/Biederman-0112.html">eutectic erosion of steel that needs an explanation; it's also http://www.journalof911studies.com/articles/WTCHighTemp2.pdf">high temperatures evidenced by iron spherules, molybdenum spherules, and vaporization of lead.

One explanation that has been suggested for the former is that sulfur present in elements of debris like drywall, concrete, and diesel fuel provided the sulfur and the long-burning fires in the debris pile supplied the heat. But could those sources of sulfur under those conditions actually cause eutectic erosion? Johnathan H. Cole, P.E. conducted an experiment and concluded that they could not:

And the evidence found in the dust of high temperatures (iron spherules, molybdenum spherules, vaporized lead) does not appear to be explained or explainable by any process in the debris fires because the dust was distributed by the collapse event, not by the burning of the debris afterward.
