Bandit Frequent Poster	posted September 15, 1999 03:15 PM Is there a easyish way to make aluminum powder im wanting to make themite i've got a chemical way to get iron oxide and 5th november's (like 4th of july for americans) comming soon so shit loads of sparkerlers.
nbk2000 Moderator	posted September 15, 1999 03:27 PM You can buy aluminum powder at an auto supply store. It's called "alumaseal". Small plastic bottle with about 20 grams of fine Al powder. Used to seal leaks in radiators. Costs about $2.75 where I'm at. Cheaper to buy it in bulk at a chemical supplier, but you can get it anytime from the store. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
Ho ju Moderator	posted September 15, 1999 04:00 PM Bandit. you need to have SUPER FINE aluminum powder and SUPER FINE Fe2O3 to have the thermite work. i know a kid who tried to make this and light it with a magnesium strip and it didn't work. The powders were dust like (maybe a tad bigger) and it did not work. ------------------ Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

nbk2000 Moderator	posted September 15, 1999 08:21 PM You can use metals as course as coffee, but you need to use a better igniter than magnesium ribbon. A 3parts chlorate/1 part sugar mix with a little alumaseal powder mixed in will do the trick. Use a paper tube filled with this mix and place it in the center of your thermite container. Fill the container up level with the top of the tube and pour a 1 inch layer on top of the thermite. Lit with fuse and you'll have a fire for sure. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
megalomania Administrator	posted September 16, 1999 01:38 PM I have it on reasionable authority that the aluminum in radiator leak plugger contains mostly some kind of wheat product and only a small amount of course aluminum... I received an email from a person who works in such a factory. I have this... react aluminum foil with hydrochloric acid to make aluminum chloride. The aluminum chloride solution is then reacted with magnesium metal to make magnesium chloride and precipitating aluminum powder. The powder can be filtered to collect it and there you go This is a waste of magnesium if you ask me, of course I like to do Grignard reactions, if you don't do Grignard reactions, you can use all the magnesium you want ------------------ Visit Megalomania's Explosives and Stuff at http://surf.to/megalomania
nbk2000 Moderator	posted September 16, 1999 03:13 PM Why go through the hassle of making aluminum with magnesium? Magnesium is better than aluminum for thermite anyways. As for the alumaseal, I've never analyzed it so I don't know what all is in it. But it burns just fine. Could wash it on a filter with water to remove anything soluble. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
VeHeMT Frequent Poster	posted September 16, 1999 06:50 PM On Jay Leno, Leno had some demonstration scientist come on the show and amog other things he brought thermite. Nothin spectactular about this except to ignite it he poured glycerine on the thermite which was in a few steel cups on a rack. Within a few seconds the thermite had taken fire; now would a simple iron oxide + metal thermite react the same way or had he added another ingredient for this reaction to occur? Potassium permanganate possibly?
nbk2000 Moderator	posted September 16, 1999 06:54 PM Must have been a permanganate/metal mix. Are you sure they said glycerine? It could have been an acid poured on sugar/chlorate. That would work too. ------------------ "The knowledge that they fear is a weapon to be used against them." www.50megs.com/nbk2000
