Source: Jensan Scientifics Pure germanium is a semiconductor with an appearance similar to elemental silicon. Germanium has been widely used for manufacturing of semiconductors. However, it was German chemist Clemens Winkler who first isolated the element and proved its existence in 1886. Also see information about the Periodic Table further down on this page. It is similar in chemical and physical properties to silicon. The most common use of germanium is as a semiconductor. Germanium is a metalloid element. The latter makes Germanium metal an important material in electronics and solar technology. Discoverer: Scientists at Dubna, Russia (1964)/Albert Ghiorso et. Extremely pure germanium crystals are obtained through a technique termed as zone refining which produces semiconductor grade germanium with an impurity of 1 in 1010.

Germanium, a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals. This was a triumph for Dmitri Mendeleev in his construction of the periodic table. A short film about the chemistry of Germanium, presented by The Periodic Table of Videos. Mendeleev predicted the existence of Germanium in 1871 as ekasilicon, and the element was discovered by Winkler in 1886. You will find many other elements that were named after people or places as you study the elements of the periodic table. Transport of thermal energy in solids may be generally due to two effects: Copyright 2020 Periodic Table | All Rights Reserved |. Like germanium, the planet Neptune had recently been discovered from predictions from mathematical data. Germanium is metalloid, which means it has properties of both metals and nonmetals. Fully descriptive writeups. To find out more, see our. From the Latin word Germania, Germany. Germanium, symbol Ge, has a Face Centered Cubic structure and Gray color. Atomic Number: 32 Germanium is a gray-white metalloid, and an important semiconductor material. ), and shape. Comprehensive data on the chemical element Germanium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Germanium. A look at what EDAX's EBSD products can detect in regards to Germanium. The forces of chemical bonding causes this repetition. There are 14 general types of such patterns known as Bravais lattices. In solid-state physics, this energy gap or band gap is an energy range between valence band and conduction band where electron states are forbidden. Mendeleev provisionally called the predicted element eka-silicon. Insulators, on the other hand, are made of a wide variety of materials depending on factors such as the desired resistance. Germanium is grayish-white in color, hard, and shimmers. All values are quoted in kJ mol-1. ), crystalline, brittle, and gray-white metalloid. Winkler's original name for germanium was Neptunium. Germanium Chemical 32 element of periodic table. Germanium. Element 32 of Periodic table is Germanium with atomic number 32, atomic weight 72.64. Storage & Handling: Keep tightly sealed when not in use.Store and use at 20 ± 4°C.
