Beware !!!!!!!!!!!!!!!!!!!
Beryllium was mentioned here. Beryllium Oxide was used in the thermal
conduction stuff HF-transistors decades ago, but this ceramic stuff can
be quite lethal. If it breaks and you inhale a few microns of the dust
there off, lungcancer can almost be guarantied within a decade !!!!
Stay away from BEO !!!!!

Interestingly enough, at these low
temperatures Beryllium is pretty good at 367.
