  Thermite - Wikipedia, the free encyclopedia
A thermite reaction is one in which aluminium metal is oxidized by an oxide of another metal, most commonly that of iron.
Thermite grenades and bombs are used in combat as incendiary devices, able to burn through heavy armor or other fireproof barriers.
Thermite can also be used for quickly cutting or welding metal such as rail tracks, without requiring complex or heavy equipment.

How convenient that you eliminate the most relevant authorities to the topic, who are structural and materials engineers.
The thermite reaction is a violent one, generating tremendous heat, accelerating the by=product molten iron away from the source.
How about responding to my central point which is that there are many official theories, not just one.

One way of lighting a thermite mix is to prepare chlorate and sucrose composition then drip concentrated sulfuric acid on it to act as a delay then the acid will light the mix.
Thermite reactions are not used in commercial fireworks but they are popular with amateurs.
Metal oxides are used as oxidizers in thermite reactions and as a color producer in the case of copper oxide.

 Self-Propagating High Temperature Synthesis
It was not until the early 1970s, after a large number of refractory compounds had been synthesized, that the full potential of SVS and the impact that such a method could have on the industrial production of ceramic materials were realized.
More than 200 different compounds had been synthesized by the late 1970s, and the Soviets believed that it was possible to produce almost all known refractory compounds.
Thermite is a mixture of Al powder and iron oxide which when ignited forms Al and molten Fe by a strong exothermic reaction.

Thermite is a mixture of iron oxide and aluminum powder.
Use of sulfur in conjunction with the thermite, for example in thermate, will accelerate the destructive effect on steel, and sulfidation of structural steel was indeed observed in some of the few recovered members from the WTC rubble, as reported in Appendix C of the FEMA report.

 [1.0] Chemical Rocket Systems
Specific impulse can be thought of as an index of the "mass ratio" of a rocket vehicle, or the ratio of payload to vehicle mass: the higher the specific impulse, the greater the efficiency in terms of the amount of payload per fuel mass.
These processes were not trivial: the ammonium perchlorate oxidizer had to be very finely and uniformly milled; all the materials in the solid fuel recipe had to very uniformly mixed; and the grains had to be poured and then cured for several days in a vacuum environment to prevent bubbles from forming.
Work was also done to synthesize high-performance solid fuels, which included proportions of nitroglycerine and a particulate form of nitrocellulose, and in some cases a high explosive known as HMX as well.

 Bryson Burke Diamond Corporation: Diamond Exploration and Mining in Canada
The research, funded largely by a company that intends to sell what it calls "cultured diamonds" for jewelry, is leading to a better understanding of how to make diamonds and other crystals not only for jewelry, but also for next-generation high-speed electronics.
The story of efforts to synthesize diamond is a tale of innovation, intrigue, error, danger, and at times downright chicanery and deception.
The whole device was capable of producing over 50,000 atmospheres and the graphite sample was surrounded by thermite which, although it could raise the temperature by 2000°C, was unstable and, combined with the alcohol, potentially explosive.

Reproducibility in performance is adversely affected by the difficulties of synthesizing and processing materials with the same particle morphology and distribution uniformity.
Concern from the DoD 2000 Weapons TARA regarding the need to maintain weapon lethality as weapon and platform size decrease continued to be addressed in efforts to synthesize, characterize and scale-up new energetic materials with increased or tailored performance and decreased sensitivity.
With the installation of a special press in FY 2001 designed to produce sample sizes of 100mm3, the feasibility of bulk synthesis on CO-derived and nitrogen HEDMs was demonstrated and initial measurements of their energy content with larger sample sizes was completed.

In this age of television-series franchising, videos, and satellite dishes, this young, embittered male gets his skewed view of us from reruns of Dynasty and Dallas, or from satellite links beaming down Baywatch, sources we dismiss too quickly as laughable and unworthy of serious consideration as factors influencing world affairs.

However, current thermite composites do not yield a higher reactive power because of the large diffusion distance between the metal fuel and oxidizer in thermite powders.

Logan received both her bachelor's (1970) and master's (1980) degrees in ceramic engineering at Tech, and is director of the Materials Science and Technology Laboratory at the Georgia Tech Research Institute.

While the conventional manufacture of titanium diboride produces carbon contaminants and large particles which are difficult to form into useable shapes, Logan says her method produces titanium diboride that is pure, free of carbon traces and easily shaped.

He discusses how the research team of Mao and Hemley got tantalizingly close in September 1989, detecting a phase change at 2.5 million atmospheres and room temperature, where the hydrogen turned dark, a predicted first step towards metallization.
At http://www.llnl.gov/PAO/NewslineStories/Hmetallization.html is a story of how Lawrence Livermore researchers were able to make metallic hydrogen at 1.4 million atmospheres and 3000 deg K. The pressure was lower than expected, probably because the temperature was higher.
