Forgive me if I'm slow but, by ATM, do you mean the Harrit et al paper? If so, it does not support your assertion.

Yes, I do mean Harrit et al. How does it not support my assertion?
 
Yeah, if you call Jim Millette's attempt to replicate it "no impact"!

Oystein, what is the relevance of energy density to the chips that were DSC-tested?

The DSC tests showed that the ignition point of the chips was ~ 430 C. This rules out primer paint.

3. Thermal Analysis using Differential Scanning
Calorimetry

Red/gray chips were subjected to heating using a differential scanning calorimeter (DSC). The data shown in Fig. (19) demonstrate that the red/gray chips from different WTC samples all ignited in the range 415-435 °C. The energy release for each exotherm can be estimated by integrating with respect to time under the narrow peak. Proceeding from the smallest to largest peaks, the yields are estimated to be approximately 1.5, 3, 6 and 7.5 kJ/g respectively.

You do understand that "energy release", "yields" and "kJ/g" all refer to energy density, right?

It goes on, page 27:
Harrit e.al. said:
It is striking that some of the red/gray chips release more energy in kJ/g than does ordinary thermite, as shown in the blue bar graphs above. The theoretical maximum for thermite is 3.9 kJ/g [27].

You do understand that "energy in kg/J" refers to energy density, right?


ergo, what is the relevance of reaction rate to the chips that were DSC-tested? Do you have any experimental results from the DSC test of red-gray chips that gives us an estimate of the reaction rate or explosive potential of the same they way they give and discuss specific values for energy denssity, and if yes, what are they?

"...You are dodging. You made a claim - back it up: What is the range of energy yield for thernites? I know, you don't."

If you look at the Bentham Paper, they acknowledge several times that the DSC results exceeded the theoretical limit for thermite.

The authors of the Bentham Paper provided this hypothesis;

Bentham Paper said:
"It is striking that some of the red/gray chips release more energy in kJ/g than does ordinary thermite, as shown in the blue bar graphs above. The theoretical maximum for thermite is 3.9 kJ/g [27]. We suggest that the organic material in evidence in the red/gray chips is also highly energetic, most likely producing gas to provide explosive pressure. Again, conventional thermite is regarded as an incendiary whereas super-thermite, which may include organic ingredients for rapid gas generation, is considered a pyrotechnic or explosive [6, 24]. As this test was done in air it is possible that some of the enhancement of energy output may have come from air oxidation of the organic component."

thermites display a range of energy yields.

What is that range? I expect numbers for a and z: "From a kJ/g to z kJ/g".

Yes, and Harrit et al. show it is irrelevant to determining the substance is thermitic.
