dave321 Posted April 26, 2021 Share Posted April 26, 2021 excluding blackpowder which is too smokey and azides, i am after a simple gas generation composition, quick acting. any obvious compostions come to mind ? maybe based on ammonium perchlorate , Ammonium nitrate possible , nitrocellulose? i guess nc as flash cotton might be suitable. looking for ideas.

Arthur Posted April 26, 2021 Share Posted April 26, 2021 There is always the "oxygen candle" from submarine use or the emergency oxygen generator from civil airliner drop down masks. High chlorate and a little fuel and some iron to reduce the chlorine content. Link to comment Share on other sites More sharing options...
Arthur Posted April 26, 2021 Share Posted April 26, 2021 Most things like small confetti canons use some kind of nitrocellulose either as a white fluff or as shotgun powder. Link to comment Share on other sites More sharing options...
Crazy Swede Posted April 27, 2021 Share Posted April 27, 2021 According to "High Explosives Propellants Pyrotechnics" by Ernst-Christian Koch, state of the art non-azide airbag comps are for example: #335 potassium perchlorate15 nitroguanidine50 Guanidinium nitrate #466.8 ammonium nitrate 6.7 potassium nitrate21.5 diammonium 5,5'-bi-1H-tetrazolate 5.0 glass fibers (SiO2) Both need strong confinement to burn quick, #3 is the fastest one. Is liquid a possible solution and gas in the form of a mixture of steam and oxygen ok for your application? Strong hydrogen peroxide (at least 40 % I think) dissociates very quickly into steam and oxygen when a small amount of potassium permanganate is added.
