It is a very important semiconductor material. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with an impurity of only one part in 10 -10 . Certain germanium compounds have a clear activity against certain bacteria, which makes them of interest as chemotherapeutic agents.
