pyroshell Posted March 4, 2013 Posted March 4, 2013 Try mixing this dud Al powder with sulfur and nitrate. (Make it into slow flash).I have some al that won't burn with KClO4 will burn with KNO3 will burn with KClO4 and sulfur. And when mixed with prilled AN, and struck with a rifle round it detonates. It also makes okay thermite.With a standard mix of 7:3 flash perchlorate flash powder when using visco fuse it would not ignite. When heating it with an open flame for extended periods of time the KClO4 will visible melt. After more heating I can start to smell it decomposing. Later after that about 45 seconds or so it will start to burn. The part that is the craziest is that part will ignite and not the other part so you will have several different deflagrations.
Alireza Posted March 6, 2013 Posted March 6, 2013 (edited) I'm just so excited and I couldn't help to come here to say that IT WORKED !!! This time with magnesium and a little bit of sulfur added.I'll upload the video of the huge explosion on youtube, soon Thanks for the advice dear pyroshell, Though I haven't completely read your post EDIT: Here's the video: http://www.youtube.com/watch?v=m4JwagKpSPw Edited March 6, 2013 by Alireza
yvariro Posted March 7, 2013 Posted March 7, 2013 (edited) It burn nice BUT please use a firebrand ignition next time or with a visco fuse,trust me it really hurt to be burned with flash powder... Edited March 8, 2013 by yvariro
Alireza Posted March 7, 2013 Posted March 7, 2013 I brurn nice BUT please use a firebrand ignition next time or with a visco fuse,trust me it really hurt to be burned with flash powder...Of course I will I'm trying to make black powder and fuse, afterwards.Thanks for the advice
zAZO9a Posted March 12, 2013 Posted March 12, 2013 i cant belleive that any way you mix flash will not work unless dampness is present.. in all the thirty sumthin years i have only had 2-3 tymes it wouldnt thrill and terrify me at the same tyme. was due to damp potassium perchlorate.the only way to mess this up is if your fingers are missing...if you cant make this and its identical to h3 .you have to be xtra carefull when making it' do not use potssium chlorate .. use diaper method and potassium perchlorate.. you can use static guard ..available anywhere. on your( cotton clothing} preferably . and spray in side baggy ..using the perchlorate is so much safer. while making h3. it is safer in as far as friction . but has been known to cause premature explosions/ however there are very few things you cant mate pot-chlorate with that wont explode.. almost anything you mix it with will cause a pyrothechnic affect. h3 is a good break charge in small shells- and a good lift charge.for most small shells.. and makes awesome fire crackers for beginners..is as much fun as flash but is lower in the bang and flash area......
