Didn't realize the stuff was reactive like pure sodium/lithium/potassium/etc. Glad it was just thought
and I wasn't going actually get and machine the stuff.

It would ignite and burn with very toxic results.

Uranium in finely divided form is readily ignitable, and uranium scrap from machining operations is subject to spontaneous ignition. This reaction can usually be avoided by storage under dry (without moisture) oil. Grinding dust has been known to ignite even under water, and fires have occurred spontaneously in drums of coarser scrap after prolonged exposure to moist air. Because of uranium's thermal conductivity, larger pieces generally have to be heated entirely to their ignition temperature before igniting. Moist dust, turnings, and chips react slowly with water to form hydrogen. Uranium surfaces treated with concentrated nitric acid are subject to explosion or spontaneous ignition in air.

This is probably the stupidest idea yet, but has anyone thought of
using depleted uranium for sparkgap electrodes? Figured if it was one
of the heaviest stable elements in the periodic table it won't
melt/corrode as easily as tungsten at high power. Does it have crappy
RF properties like steel? Probably a moot point in a few years when
DRSSTC's take over, but still kinda courious.
