I actually got some BaCO3 because BaNO3 is bad to ship but now that I have it I cant find anyone else using it, so I Have no idea where to start or what oxidizer to use with it, Im afraid without NH4NO3 it might not turn green, all I have is KClO4 and KNO3 and the usual C, S, basic color comps.

I know find a chemical for a use but it seems a waste.

Oh, and, hi everyone whats new.

Find a chemical for a purpose not a purpose for a chemical. It is used in green comps but usually in conjunction with Ba(NO3)2. You are best off getting some HNO3 (even dilute will work) and making your own Barium Nitrate from it.

There is one composition on the PFP database that has barium carbonate but not barium nitrate. I do not know how well it works.

You really need to go through those databases before you buy chemicals so you know how often they are used and in conjunction with what.

Um your not going to see any formuli using ammonium nitrate for stars, especially a colored star.

Go look through the newsletters at skylighter.com and look for something on radiant green stars, the original formula uses only barium carbonate for aa colorant.

Oh and I made a comp using it for a colorant too, its one of my "go-getters on crack" comps so your cant have it, its top secrete. And yah its green.

Found this on the old APC site, no idea how good it works.

Potassium Perchlorate 70
Red Gum 9
Barium Carbonate 15
Charcoal 2
Dextrin 4

I seem to recall parlon or another chlorine donor being used in carbonate based star compositions.

Actually theres one on the PFP database if you have any magnalium;

BaCO3 : 19.5
KClO4 : 30
Red Gum : 4
Magnalium, 100 mesh : 30
Dextrin : 4
Parlon : 12
Boric Acid : +0.5

I really don't think there is a ton of Baco3 comps...i would just use some Hno3 like Minion said...but that would be very hard to dry out. I tried a small bit of it....and not even the oven at 300*f will dry it out enough :( or in my cause anyway...I'm sure if you got some super water absorbing chemical and heated the BaNo3 at the same time..may work better. still a pain in the ass though.

It should be able to be formed from barium carbonate and ammonium nitrate... probably heated near molten, but I'm not 100% sure... maybe a rolling boil solution.

BaCO3 + 4NH4NO3 ---> Ba(NO3)2 + (NH4)2CO3

(NH4)2CO3 ---> 2NH3 + CO2 + H2O
The idea is that the ammonium carbonate decomposes driving the equilibrium to favor barium nitrate. Supposedly you can do the same thing but with ammonium perchlorate instead of nitrate to get barium perchlorate... which I'm very interested in. However I am not 100% on either of these cases.

If you are going to attempt something like this I would do it on a hotplate with decent temperature control with an extension cord and outside away from buildings etc. The idea that it could det in either case is not far fetched at all. I would be more scared when using ammonium perchlorate.

I would try boiling an aqueous AN + barium carbonate solution for a few hours and keep adding water as it boils off... Simmering would be better because if barium nitrate does form you don't want it splattering everywhere, it is quite easy to get barium poisoning from barium nitrate. Mumbles got it once IIRC.

Thanks, I wouldnt try making BaNO3 Im afraid I'd hurt myself, but I did mean Ammonium Perchlorate not ammonium nitrate, sorry, you are right about it not being in stars, and the nitrate appears to be much more soluable making it much more dangerous.

I have that one comp from skylighter, Ill try it and tweak it and let you know as usual I guess.

You really need to go through those databases before you buy chemicals so you know how often they are used and in conjunction with what.

I always check the problem was I couldnt find any other chems that supported the color GREEN, except barium salts. anyways, and I am trying to stick to organic fuel stars until I get much better, then Ill try metallic. I think there is a metallic fuel comp thats green, but it might also have Barium.
