Once upon a time there were galena crystals. However the first
electronic virus struck and changed the crystalline structure of
galena crystals. The American manufacturer who was strck by this
plague sent samples to a German manufacturer who was still able to
produce good crystals, and his plant became infected. Soon no one was
able to make "working" galena crystals, and radios had to switch to
selenium or germanium.
With modern materials science techniques, it should be possible
to make galena crystals in an "uninfected" environment, and then
encapsulate them. Anyone want to try?
