It is just in experimentation faze but I think it could be practical.I just mixt 10 g of S and 15 g of C(BBQ) and maket it a slurry by adding to it a solution of 50% AgNO3.Then spread it on a piece of glass and in 2 hours it is solid.After that I just make it the granulation I need and it ready.It burns much faster than normal granulated BP.Did somebody tryed this or I am the only one ?

Expensive lift charge hehe. Normal black powder is fast sh*t and works for a thousand of years now. So I guess there´s absolutely no need for such a "experimental" and expensive type of lift charge.

I´d like to see it "in action", though.

And I'd like to collect the smoke/ash and sell it!

Yeah, not very economical, but a good rather exotic mixture. Be careful though, Silver Nitrate can be used to make very powerful explosives, not like what your making but other mixtures are very dangerous.

But well done, can you get some burn rate tests done and then it can be compared to BP.

You say 50% solution, is that 50% w/v (worst unit ever) or 50% saturated? I'm just thinking this because you have basically not given a weight for one of the components, it could be anything for what we know.

Silver Nitrate is light sensitive, so you could end up with a useless composition after extended exposure. Plus this mix would be hygroscopic, and..... silver nitrate burns the skin. So gloves would be a good idea, so would eye protection if using a 50% solution.

Along with cost and instability, add toxicity. 2 grams of AgNO3 is a lethal dose by ingestion, I imagine much less than that by inhalation will do amazing things to your lungs. ( as well as opaquing them interestingly on X-ray ? ) For instance, in the Soviet gulags, prisoners would add silver filings to tobacco, and deliberately give themselves heavy metal poisoning and lung damage that would mimic tuberculosis convincingly enough to get off work detail and into a hospital.

I got the ideea.It's just a mixture that I wanted to post it here.It is not good at pyro but atleast it is something.

[icarus]

if you want relly cheap pyro you can use sodium nitrate instead of potassium nitrate but it absorbs water i use ammonpulver as a smokeless lift powder for shells but that absorbs water too ( i cant spell deliquescent ) nitrate /sugar rockets tun to slop if not used quickly but in my linimg paper and wallpaper paste cases with ground cat litter plugs its cheap safe pyro

If you want a really fast, and somewhat exotic lift charge try the Lithium nitrate/potassium nitrate eutectic. It is supposed to be supremely fast and bristant. It might be the sodium/lithium/potassium nitrates eutectic, but it definatly has lithium it in. Somewhat more affordable than silver nitrate.

The two attributes that have to be improved are always performance AND cost.

Is there much value in creating a compound that we cannot afford to use.

The Chinese have taken the majority of the fireworks market because they produce fireworks cheaply. There is no point in making compounds so expensive that they are not affordable!

[icarus]

thats why i use ammonpulver to use ammonium nitrate or sodium nitrate based bp and im trying kno3/sugar rockets to save my bp im making solid fuel blocks you drop into the tube I must get round to posting a thread on rocket forum for info on kno3 and polyester grp resin fuel to save the effort of casting molten material
