Re: 20MM Hexagon Ammunition
Hello,
@ Wotan excellent site, thanks! @ Juha I'm not sure that i have understood you correctly, but I don't think that aluminium powder itself, increases the amount of flash. Aluminium is a good heat conducter with a low melting point, which helps to increse the energy distribution in the composition and simultaniously the detonation speed. True, aluminium dust is used in flash powder (old fashion photography), but it is used as a fuel - to produce the flash a strong oxidizer must be added (e.g. potassium chlorate or perchlorate). If you were refering to incendiary rounds, I think that the Luftwaffe also used thermite (simple mixture of aluminum dust and iron oxide) or white phosphorus to produce the incendiary effect. best regards, Tomislav Last edited by Tomislav Haramincic; 14th June 2006 at 02:43.
