A bunker-busting shell that gets so hot on impact that it burns its way through concrete and steel is being developed by the US Navy's Warfare Center in Virginia.
The shell contains a mixture of aluminium polytetrafluoroethylene (PTFE) and perchlorate oxydiser, moulded together into an aerodynamic shape. To prevent the mixture from disintegrating as it travels through air at high velocity the shell is wrapped in a soft Teflon tape, which is wound tight under high tension, heated and topped with epoxy glue to prevent unravelling.
Its high-velocity impact acts as a catalyst, forcing the two chemicals together in a red hot reaction. The projectile gets so hot so fast that it should instantly burn its way through armour plating or other defences.
And the burning shell would avoid the environmental pitfalls of radioactive depleted uranium - currently the most common material used in armour-piercing shells.

put an explosive in it? if the cap was metal it would then basically act like a shaped charge..in fact it is sort of acting like a shaped charge, but instead of using holt molten metal to makea jet through its kinda...turnings itself in to er..molten metal to burn though?
