petroleum Posted November 18, 2011 Share Posted November 18, 2011 Dear all!At the moment I have a possibility to get some quantity of metallic antimony(I hope, that it can be crushed in the powder using steel mortar of ball mill). I do not have any experience working with this material. But in literature I have found some formulas using metallic antimony and these stars reported as electric white stars. Is there somebody who have experience in antimony based mixtures?Is there some critical points regarding toxicity? What effects can be expected?What type of formulas can be used(nitrate, chlorate or perchlorate based)? Thank you! Link to comment Share on other sites More sharing options...

Dont breathe the dust, don't eat, smoke or drink around it and wear gloves when handling it. -dag Link to comment Share on other sites More sharing options...
TheArchitect23 Posted November 18, 2011 Share Posted November 18, 2011 (edited) well, antimony in chunk or brick form is used to slightly strengthen lead in my normal daily use.now i am melting it, you want to make it a powder.it is relatively soft for a metal, so crushing should be easy ( edit )depending on how it has come shipped to you.

Potassiumchlorate Posted November 19, 2011 Share Posted November 19, 2011 Antimony trisulfide stars are a cheap and pretty acceptable substitute for white Mg stars for star mines and smaller stuff on or near the ground. Would be interesting to see the pure metal used, though. Link to comment Share on other sites More sharing options...
a_bab Posted November 19, 2011 Share Posted November 19, 2011 Antimony metal has been used indeed, as it burns with a white color. Some "white fires" formulas from the past mention it. Those old pyrotechnists tried about anything in their compos back then. I really see no advantage using it, giving it's toxicity. I'm saying this because I also could have got some in kilo amounts for free but I said "better not". It was the toxicity that put me off, although I have no problem using K dicromate for instance since I understand the risks. I prefer magnalium for white stars.
