Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. The development of the germanium

Germanium has been always considered as a strategic metal for most governmental agencies and its supply and prices are often controlled in the form of stockpiles. Worldwide supply of Germanium ranges around 100 tons per year, with around 60% coming from zinc refining sources, and the rest mostly originated from fly-ash processing.

Germanium ores are very rare. They are found in small quantities as the minerals germanite and argyrodite.Germanium minerals are also present in zinc ores, and commercial production of germanium is carried out by processing zinc smelter flue dust. It can also be recovered from the by-products of combustion of certain coals.

Germanium is available through the treatment of germanium dioxide, GeO 2, with carbon or hydrogen. The extraction of germanium from flue dust is complex because of the difficulty in separating it from zinc, which is also present. GeO 2 + 2C → Ge + 2CO. GeO 2 + 2H 2 → Ge + 2H 2 O. Very pure germanium can be made by the reaction of GeCl 4

Germanium first came to prominence in the late 1930s with the development of the solid state electronics. Today, germanium metal is commercially used to manufacture infrared optics and photovoltaic cells, while germanium dioxide (GeO 2) and germanium tetrachloride (GeCl 4) are used in the production of fiber-optic coatings, PET plastic, specialty gases and phosphors.

Jun 30, 2016The atomic number of zinc is 30, which means that all zinc atoms have 30 protons in their nuclei. A neutral atom has equal numbers of protons and electrons, so a neutral atom of zinc would have 30 electrons. The electron configuration of a neutral zinc atom is #1s^22s^22p^63s^23p^63d^104s^2#..
