XenoN Posted August 31, 2006 Share Posted August 31, 2006 I am looking for a source of strontium nitrate. I have heard you can extract it from road flares. I have plenty of those around but im not sure how to extract it. Link to comment Share on other sites More sharing options...

Frozentech Posted August 31, 2006 Share Posted August 31, 2006 I am looking for a source of strontium nitrate. I have heard you can extract it from road flares. I have plenty of those around but im not sure how to extract it. Out of curiosity, why not just buy it ? It's one of the cheapest pyro chems there is, and you can get 99.99% pure Sr(NO3)2 for $4.50-$7.00 / lb a lot of places. Ebay,Skylighter, Firefox, etc.. Readily available, shippable, and a lot less hassle. I know, making things from 'scratch' is part of the fun of pyro, but at some point you have to weight the value of the time you spend doing things also. Especially with coloring agents, purity counts for a *lot* as well. Link to comment Share on other sites More sharing options...
XenoN Posted August 31, 2006 Author Share Posted August 31, 2006 I did search all I got was that strontium nitrate makes up 60% of the flare as well as other oxidizers. I have alot of them around my house and have no other use of them. Link to comment Share on other sites More sharing options...
Pyrohawk Posted September 1, 2006 Share Posted September 1, 2006 Well...you should look a little harder for stuff... But I'm in a good mood and I used Sr Nitrate from flares when I first started to. Just dissolve all the contents of the flare in boiling water. Sr Nitrate is the only chem in them that is water soluble so the rest will float around in it. Just filter this solution througha coffee filter to get rid of the extra junk. Now you should have just a clear solution... it will looks just like water. Now boil it till all the water is gone. This will take a while..... maybe a couple hours or so. So put it outside, set it to boiling, and check on it. When it gets to where most the water is gone it should have the Sr all over the bottom and sides (kind of a slush). Take it off the heat..... scrape everything out and let it dry under a heat lamp or something. Then crush it up to a fine powder when its dry.
