Jack Cole Reports Reactor Meltdown in Experiment

I just noticed that the ingredients used correspond at least partly to Thermite:
A mixture of iron oxide
Fe2O3 (rust) and aluminum powder. When it is ignited the aluminum
powder reacts with the O3 part of the rust in a highly exothermic
reaction, the resulting product is molten iron. Thermite is commonly
used in welding, because the molten iron has the ability to seep into
cracks in metal.

Termite demand aluminum not it's oxide.
alumina is the result of the reaction.I considered if nickel can be the target, but in fact it seems the opposite.
Termite reaction is used to produce ultra-pure molten Nickel from oxide. -
I forgot the aluminum from the LAH...
yes that is a possibility. now question is the quantity of heat produced by 1g of LAH+Fe03by first bet however is that the alumina is not pure and melt at lower temperature

Click the link to the "source" article at the bottom of the original LENR Forum post. Quoting:
"I was using INCO type 255 nickel, TiH2, LiOh, KOH, aluminum powder, and Fe2O3. Good idea on the small amount of fuel which should cause some localized melting."
[Relevant text underlined and made bold by Longview: quote apparently attributed directly to Jack Cole]
Longview comment also amended in "edit" mode: Clearly ingredients are not quantified at all here , but I have to stand by Thermite, until otherwise informed by the builder as above. Was the builder trying to make aluminum oxide in situ? Why? What was the rationale? I certainly did not see any question showing Thermite ingredients presented where I was able to critique it. As it stands the "experiment" proves only that Thermite can melt and burn up nearly anything -- many of us already new that.

sorry I mixed with another experiment based on LAH.
The mix is strange. It contain the components of LAH (is it the rationale) but some more too... Ti K...
You are right, Al-Fe2O3 termite reaction seems the most energetic inside.from
http://www.wolframalpha.com/in…+2+Al+-%3E+2+Fe+%2B+Al2O3
it seems 1gram of thermite mix produce 4kJ
but one gram of alumina need 16kJ to became liquid...some mix of alumina change phase around lower temperature... It was discussed (where?)
I've found that aluminosilicate phase diagram... but is the tube made of silicate too?
http://www.britannica.com/EBch…the-alumina-silica-system
http://www.princeton.edu/~cml/assets/pdf/7558aksay.pdf
they say the 5% silicate is a mix of alumina and liquid starting at 1825 (silicon dioxide melt at 1600C)maybe the 5% of something (silicate?) else caused part of the material to melt...
it seems quite classical melting?
as said jack Cole, he nee to know what is the 5% beside alumina.

Maybe that explains why the "silicate" or aluminum silicate tube is only "glazed" and somewhat distorted looking. In other words the temperature (degrees C) of the Thermite reaction may well be much hotter than the silicate melting temperature, but the quantity of heat (kJ) was not at all sufficient to melt, vaporize or burn everything (the mass or moles of substance) there. The Wikipedia article (no controversy, so in that case perhaps an OK source), indicates there are many types of Thermite. The hottest of the Thermites listed there is the Iron (III) oxidizer with aluminum as fuel, [btw, the most common form of Iron (III) is Fe2O3]--- reaction temperature of up to 2500 degrees C. That is favorably over the melting point of aluminum oxide (Al2O3) at a bit under 2100 C.
Of some importance: Thermite / Thermit is still the brand of a commercial enterpirse. its products unlike aspirin, may still have trademark exclusivity status even though there is widespread popularization of the term. I see this link: http://www.goldschmidt-thermit.com/en/ which derives its name from the originator of the technology around 1893.
I see no aluminum oxide per se listed in the ingredients of the original Jack Cole sentence I quoted from the "source" document. But, certainly aluminum oxide can easily be found in refractory ceramic tubes, such as the pencil heater or spark plug insulators Nickec and perhaps others mentioned. Al2O3 presence might act as a surface catalyst (immobilizing electrons as many oxides tend to do) that may incidentally or intentionally enhance any LENR produced.
