I know I am new here hope everyone will welcome me but the big tests I have seen done with the thermite to get the reaction consistent they go to a junk yard and buy an old magnesium VW engine block and grind enough filings off and then mix in roughly 25 percent magnesium fine filings then they ignite it with magnesium strip paper or even a sparkler I've seen it lit with five sparklers all together buried half way and run like heck. from my understanding the added magnesium helps to ensure a full reaction just remember to clean the engine block before grinding you need to remove all old carbon and oil primarily oil.

Now explain shaun why you need to clean the oil because he said it wont blow in your face.

Forums and places that discuss thermite and incendiaries (I am not saying this one) were actually run by the intelligence agencies like FBI. Their primary method of using these honey pots to attract wouldbe terrorists, arsonists and criminals was to create such forums that they actually ran and had full control of.

Since 911, other type of agencies like CIA were in desperate need of PATSIES from islamic countries who they can frame and ship to guantanamo to satisfy the scare needed to maintain the false credibility in the "war on terror".

Under both these circumstances, the forum discussion will never get to the correct engineering applications and never be relevant to it. Rather it will in the former and the latter case, promote some glitter about it and some very primitive and obsolete and uneconomical techniques that would make real scientists blush with shame.

I have interest in thermite primarily for engineering applications. I am still waiting for a small study group where real engineering information can be exchanged and like an MS thesis or Phd thesis, the subject can be studied and techniques developed with safety and economics.

Let me add my last post to sharpen focus:
==============================

Not to sound deprecating, most replies are like: Its not that hard ...

Show us your procedure in a youtube video.

We know that many businesses are being promoted by hobby marketing. It is very hard to tell who is who.

First of all, paint Aluminum is the MOST UNSUITABLE form of Al for thermite. It is flakes. It possibly has organics that can cause it to blow in your face. The filings are not suitable either and they can injure your lungs. The grinding produces material that has non-uniform morphology and heavily contaminated by the alumina or silicon carbide of the wheel. Also if there are organics, then it will blow in your face.

Based on these solid facts, of which I am 100% sure, I am not sure if the promotions are real experience or speculations.

Please show us a video.

There are other fallacies and solutions which I will post at a later date.

However, there are a number of videos that have appeared recently on the internet on "thermate" in connection with Steven Jones and Eric Hufshmid where they claim that government or someone used this material to cut the pillars of WTC buildings.

They are mentioning something called nano-thermite which can evaporate the steel.

Check out how dangerous this material is and how useless an experiment is without a detailed analysis based on enthalpies, and a prolonged literature study.

I will work with anyone on these experiments, however, only along scientific lines and not just a thriller toy hobby.


I urge everyone (if you are in serious engineering development) , lest you are visited by FBI, to have your defense ready. Namely, deposit an affidavit with a judge, on your intents or call your local fire department and discuss in writing with them.

Or president bush in desperate need of "terrorists" may declare you a "non-enemy combatant" and ship you to guantanamo.

cheers

"paint grade aluminum" is unsuitable for Thermite....
Really?! I'm using a paint/epoxy grade Aluminum for my reactions and it works very nicely. Maybe I'm thinking that epoxy grade is 400 mesh -- anodized but still nicely flammable :)

The flake was too much oxide on its surface and is wasteful. the flake is made by a process to prevent agglomeration and that requires adsorbed organics. Why dont you list the manufacturer, name, address phone no and also a video of thermite being done by you step by step. You dont have to show your face if privacy is the issue.

anodized ??? does nt make sense for anyone to anodize flakes. how to make electrical contact ?

The best particle shape for thermite is spherical with a special type of surface, but i will drop that info after you show what you are doing.

Put your exact recipe and method first in a writeup and then plz make a video if you can. I can try to duplicate your exact method if you give me all the methods and material sources, manufacturer name etc.

you can also produce tungsten with this reaction.

but he has to give you the exact manufacturer of the flake before you "CAN" try it.

The thermite reaction is quite simple and we have several old threads in the archives. It is unlikely that anything new will come of this thread so I am closing it.
