Germanium Facts

  • Germanium is metalloid, which means it has properties of both metals and nonmetals. Other metalloids on the periodic table are boron, silicon, arsenic, antimony, tellurium, and polonium.
  • Germanium is one of the few elements that expand when it freezes, just like water.
  • The name “germanium” comes from the Latin name for Germany. Clemens Winkler, a German chemist, is believed to have found the first substrate of germanium in 1885.
  • The existence of germanium was predicted by Russian chemist Dmitri Mendeleev in 1869 after he developed the periodic table of elements.

There Are Multiple Forms

When it comes to germanium, there are five naturally occurring isotopes. They are germanium-70, germanium-72, germanium-73, germanium-74, and germanium-76. Isotopes are two or more forms of an element with each differing from each other according to their mass number. The mass number is the number located to the right of the element, which in this case is 70, 72, 73, 74, and 76. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. At least nine radioactive isotopes of germanium are also known.

It Has Many Uses

Germanium first became important for its use in semiconductors. In fact, semiconductor use accounts for 15% of all germanium used and produced. Even more popular for germanium is its use in the manufacturing of fiber optic systems. Those account for about 40% of its overall production in the United States. It is also used to make specialized glass for military applications.
