Metal germanium

Technical characteristics

The element of the 4th group of the periodic system D. I. Mendeleev, chemical symbol Ge. Atomic number 32, was opened in 1886 by a German scientist Winkler, who named the element after his homeland — Germany. In nature, it is not found in a free form, but only as an impurity in sedimentary rocks, ores of tungsten, Nickel, silicates, coal, thermal waters, peat. Accumulates in algae.

The proportion Of 5.33 g/cm3
Atomic mass 72,59
The degree of oxidation +3,
Melting point 937 °C
Boiling point 2830°C
The specific heat of fusion 36,8 kJ/mol

This low-melting metal is characterized by increased brittleness and melting point of 937 °C. however, it is a classic semiconductor and is used in the production of electronics and electrical engineering. With regard to alloys in Germany, they have good resistance to aggressive influence of acidic environments. This quality is appreciated by industries such as experimental physics and chemistry, instrumentation and mechanical engineering.

Application

This element is used in the form of high-frequency single crystals for the manufacture of diodes, photoresistors and photodiodes, sensors, parts x-ray apparatus, spectroscopes. In jewelry also used this element, due to its adaptability. Some alloys of germanium are used as anticorrosion coatings or solders.
