Sizzler:
I think one of the most interesting aspects of the WTC microspheres is that many exhibit a combination of mainly Fe and Al with relatively low O. Thus these particular microspheres appear to be an iron-aluminum alloy. This is difficult to explain in terms of production from welding or cutting debris.
It is also important to note that the composition of thermite reaction residues depends on the stoichiometry of the reactants. For example, a 1:1 mass ratio of Al and Fe2O3 yields Al2O3 and Al2Fe in a 1:2 ratio; however, a 1:3 mass ratio of Al and Fe2O3 yields Al2O3 and Fe in a 1:1 ratio. Interestingly, if Fe is well in excess as in a 1:4 Al:Fe2O3 starting ratio, no Al2O3 is formed but instead we get FeAl2O4 which is the
mineral phase hercynite.
This is why an X-ray diffraction analysis of the microspheres would be useful.
In any case, the microspheres reported by Jones (so far!) appear to be quite low in aluminum, say typically less than 12 at % Al, which is NOT consistent with the compositions noted above.
Finally I should mention that spherical Al2O3 particles are found as inclusions in thermite welds so you would expect to see Al2O3 microspheres in thermite reaction residues. I believe Al2O3 particles are conspicuous by their absence in Jones' samples.[/QUOTE]
I agree, the lack of Al203 is conspicuous, ex specially since Joneses theories rely on thermite powered oxygen cutting devices!
Not only should Al203 be abundant when such devices are used, but Fe3O4 as well should be evident in great abundance.
I must point out though, that nano aluminum would produce Al203-Fe micro spheres.
Thermite powered oxygen cutting would produce Al203-Fe3O4 micro spheres.
Electrical arching can produce Al-Fe micro spheres with very little oxygen, because the spark produced expands the air away from the particles preventing the Al-Fe from undergoing oxidation with atmospheric oxygen.
Micro spheres produced though Electrical arching in circuits could be built up over years though.
An X-ray diffraction analysis is the only way to tell what the micro spheres actually are composed of and to give an indication of the actual source.
I now believe the Micro Spheres to be a wild thermite goose chase, however I will give Jones the benefit of the doubt until the Diffraction analysis is done.
I really wish Jones would actually build a thermite oxygen cutter and test it to see if it matched the evidence, that he has and of the cut patterns on the columns that he says were cut with one, it would save us all a lot of time.
Well Dr. Jones I await the Diffraction Analysis, hope you will publish it before I die of boredom.
