More info:
As with all rare earths, Terbium is present in the entire earth's crust, though its concentration is very tiny (less than 0,1 ppm), since it is never extracted alone, but mixed with other minerals. The main supplies of Terbium are in the South of China, but this metal is in short supply from 2012. Terbium is also used in alloys and in the production of electronic devices. For this reason, the availability and access to Terbium is a source of concern for most industrialized countries as new technologies, which are based on electronic devices, need large quantities of Terbium.
