Mostre de compuși ai germaniului preparate de descoperitorul elementului, Clemens Winkler În raportul său Legea Periodică a Elementelor Chimice din 1869, chimistul rus Dâmitri Ivanovici Mendeleev a prezis existența unor elemente chimice necunoscute, inclusiv cea a unui aspect care ar fi completat un loc vacant în grupa carbonului din Tabelul Periodic al Elementelor, plasat între siliciu și staniu.
Works by using and properties Makes use of and Qualities Impression explanation Germanium was used in early transistors comparable to the one particular showcased right here. Overall look A silvery-white semi-metallic.
Germanium minerals will also be existing in zinc ores, and business production of germanium is performed by processing zinc smelter flue dust.
Several metals may be used for reflecting coatings of infrared mirrors, particularly copper, aluminum, silver, gold and stainless-steel, in addition to several metal alloys such as chrome–nickel. These are Typically created as 1st surface mirrors.
Acest factor nu are o funcție essentială pentru organisme, iar unii compuși organici ai germaniului au fost testați ca și posibile produse farmaceutice, însă fără nici un rezultat. Comparable cu siliciul și aluminiul, compușii germanici tind să fie insolubili în apă, având astfel un potențial scăzut de toxicitate orală.
Hold the plates inside of a dessicator, the significantly less water the higher, although the plates are insoluble to h2o.
At the time silicon took about, it click here may appear that germanium could be relegated to the backwaters of chemical obscurity being an also-ran that was now not value employing.
The process of generating a visible two-dimensional image of a scene that's depending on differences in thermal or infrared radiation within the scene achieving the aperture from the imaging machine.
Dampness-protection AR and BBAR coatings can be found for a variety of wavelengths or wavelength ranges within just KCl’s transmission range.
Tailored from NIST Chemistry WebBook. Figure (PageIndex 17 ) illustrates the result of particles getting way too huge and scattering light-weight. To remedy this, remove the mull and grind additional or else use the solvent deposition approach described before.
Here you can submit concerns and comments. In terms of they get approved with the author, they will surface over this paragraph along with the writer’s reply. The creator will make a decision on acceptance depending on particular conditions. In essence, the issue need to be of adequately wide curiosity.
Utilizările curente ale germaniului includ încorporarea sa în sistemele de fibră optică și celule solare. Compușii germanici sunt de asemenea utilizați ca și catalizatori, precum și materiale pentru nanofire. Acest element formează o gamă largă de compuși organometalici, precum tetraetilgermanul, de asemenea util în chimia organometalică.
It truly is similar to a A technique movement valve in the h2o pipe - electrons can stream from the heater for the anode, but not the opposite way spherical.
Germanium is also used being an alloying agent (adding 1% germanium to silver stops it from tarnishing), in fluorescent lamps and for a catalyst.
