Flash powder is a pyrotechnic composition, a mixture of oxidizer and metallic fuel, which burns quickly and if confined produces a loud report. It is widely used in.
This is a reasonably safe, easy to make, high powered flash powder, suitable for use in electrically triggered pyrotechnics xisf.org stays reasonably stable under.
I've been toying lately with the idea of using about 25 grams of flash . Mea culpa, the velocity of flash powder is 2000 meters per second, not. HOW TO MAKE DARK ALUMINIUM (for flash powder) Abstract: The critical energy Ec criterion developed by Walker and Wasley for predicting the response of bare, heterogeneous explosives to flying-plate impact, is modified for application to flat-nosed rods and spherical projectiles. There is pressing and there is deadpressing. That is the very reason it did not perform. Again, thanks for the advice and the imput. It's "slow" compared to organic HE's, of course, but it's extremely fast compared to BP. I believe Magnesium can produce greater luminosity, and can be more brissant, thus a sharper crack, but this flash powder velocity with the disadvantage of being the most unstable fuel 'regularly' used in fireworks, and due to this, it's used only rarely, with stablisers, and generally considered unsuitable for long term storage.
