Germanium tetrachloride is used as a dopant - or additive - to increase the refractive index in the silica glass core of fiber-optic lines. Germanium is a non-toxic metalloid that is chemically alike with tin and silicon. Technically, germanium is classified as a metalloid or semi-metal. Boron, germanium, silicon, antimony, arsenic, and tellurium are the six most widely recognized metalloids. History Germanium is named for Germany, where Clemens Winkler discovered it in 1886 in a compound called argyrodite. Atomic Number: 32 Germanium is a gray-white metalloid, and an important semiconductor material.

In the visible light spectrum, standard glass is almost completely transparent, and the metalloid germanium is almost completely opaque. Efforts have been made to grow the commercial market for germanium-based IR systems, such as in high-end cars, but nonmilitary applications still account for only about 12% of demand. Germanium. sites. ProTip: if you find yourself hiding from authorities looking for you with an IR camera, your best bet is to find a large cardboard box and make sure you're not too close to the surface. Germanium has been said by many to be a metal, but it is only carrying characteristics of a metal so it can be called a semi-metal. An estimated 30% of the world's annual germanium production is recycled from scrap materials, such as retired IR lenses. By 2000, high-efficiency PVCs and light-emitting diodes (LEDs) dependent upon germanium substrates had become large consumers of the element.

Unlike the big business interests of most of their big-name corporate competitors, Skullcandy was born from a simple human moment. It���s hard, grayish-white, and lustrous. In pure form, the element is a grayish-white metalloid. The development and expansion or fiber optic networks in the 1990s led to increased demand for germanium, which is used to form the glass core of fiber optic cables. Boing Boing is published under a Creative Commons The metalloid is also intrinsically semiconductive. This element has an interesting anecdote associated with its discovery. Germanium's unique characteristics include its transparency to near-infrared electromagnetic radiation (at wavelengths between 1600-1800 nanometers), its high refractive index, and its low optical dispersion. Germanium wafer in semiconductors is found to have better properties compared to silicon in some applications. Like most minor metals, germanium is produced as a by-product of base metal refining and is not mined as a primary material. But considering how fast technology… READ THE REST, Skullcandy has carved out an interesting lane for itself in the ultra-competitive audio earbuds and headphones market. Ultimately, this resulted in the metalloid being used as a key component of infrared (IR) lenses and windows. Metalloids can be defined as chemical elements whose physical and chemical properties fall in between the metal and the non metal categories. 3. The focus of this section is on the recognised metalloids. Until Teal, no one had been able to produce silicon with a high enough purity to replace germanium, but after 1954 silicon began replacing germanium in electronic transistors, and by the mid-1960s, germanium transistors were virtually non-existent. Metalloid Carbon group Germanium Chemical element Semiconductor. Technically, germanium is classified as a metalloid or semi-metal. Polonium 5. Call it the 'seven-year itch' of technology. Germanium was discovered by Clemens A. Winkler in 1886, in Germany, in a mineral sample from a silver mine. But, once you've spent a lot of time with that new addition, it can start to lose some of its luster – and your eye starts wandering. See more. It turns out the same phenomenon can happen with dry ice as it sublimates. SiGe transistors have greater switching speeds and use less power than silicon-based technology. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbours silicon and tin.
