Look at the pictures again. Do they show all spheres or is some unreacted red chip material visible? Yes or No, Turbo?
None of the chips, as received
showed any partial reaction at all. That means that they had not failed in an attempt to use them. They hadn't
failed in action. But then we see that the samples failed to react completely when tested, i.e., there was still red chip material after the reaction.
This is a 100% failure rate.
Now about the iron containing spheres. Note that they are not all iron. There are other elements in there, too. What this means is that they have a
complex molecular structure whose real melting point depends on that same structure. Let's compare the melting points of iron compounds to iron. Iron
melts at about 1535*C. FeCl3 melts at 306*C. FeSiO3 melts at 1146*C, FeS2 melts at 1171*C, all the nitrate hydrates melt below 70*C, and the nitrosyl
carbonyl melts at 18.5*C. This is a wide melting point range of iron containiing material, isn't it?
What is the molecular structure of the spheres. If you don't know, you can't know the formation temperature, can you. I have already shown that
combustion is most of not all of the energy release from the chips. What is the binder made of, Turbo? If you don't know what is burning, you don't
know how hot it is, do you and since you don't know what the spheres are, you don't know their formation temperature, do you?
Now tell us about the compositions of the spheres and their formation temperatures.
Tell us about what is burning at 440*C and how hot the flame is.
Then we will be able to determine if the flame is hot enough to produce the spheres. Until you do, your arguments are groundless.
Of course, if all we want to do is to show a thermitic reaction, we should get some competent scientists to run the DSC under inert.
"Oh Turbo...come on Turbo" answer the questions.
