Germanium is especially a byproduct of zinc ore processing. It is a difficult, grayish-white element; it's a metallic luster and exactly the same crystal construction as diamond; and it is actually brittle, like glass. In addition, it is important to note that germanium is often a semiconductor, with electrical Qualities involving These of th
This has led lots of to analyze employing Ge’s indigenous oxide as being a passivation layer in Ge products. Ge’s native oxide is generally published as GeOWith greater performance as a result of the upper absorption of germanium in photodetectors versus standard products for example silicon, much more and greater information and facts could be
For use in Digital products, germanium ingots or billets need even more purification, which normally is effected through the system of zone refining. The very pure germanium is then melted and “doped” because of the addition of moment amounts of arsenic, gallium, or other elements to supply sought after electronic properties. Eventually, one cr
Germanium is mostly generated from sphalerite zinc ores but is likewise known to generally be extracted from fly ash coal (developed from coal electricity crops) and several copper ores.Nghiên cứu của FDA đưa ra kết luận rằng germani, khi sử đụng như là chất bổ sung dinh dưỡng, "thể hiện một số nguy Helloểm
