Interesting indeed. Thanks, Karl Arne. So Nitrogen doesn't form a
compound with Zr, the Zr acts as a N2-sponge?
Haveyou ever seen a Zr gettering wire wrapped around a a
thoriated-tungsten filament? Have you ever observed that the leakage
current of a 3-500Z that has long been in storage decreases after the
filament has been lit for 100 or so hours?
