The world's largest producer of refined Germanium is China, which accounts for about 70 percent of the over 150 metric tonnes produced worldwide each year. Our Germanium Buyback Price: $885 per half kilogram. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. Germanium is widely used in electronics, serving as an excellent semi-conductor for components on different circuitry. Our Germanium Sell Price: $915 per half kilogram. Germanium chloride is a bond between a metal and a nonmetal. In its metallic form, germanium is … As with a number of the other minor metals, germanium never exists as the "native" metal, but is to be found as a trace element in a variety of different, often metal-bearing, minerals and ores. Germanium is a chemical element with symbol Ge and atomic number 32. The chemical symbol for Germanium is Ge. It is found quite often in fiber optic networks and infrared optics. Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context. Thus, this compound has an ionic bond. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. Germanium is a silvery white element and appears most commonly in a brittle crystalline form. Our germanium tests at … Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Germanium is a silvery white metalloid. This is a 2-by-3 centimeter piece of polycrystalline germanium, weighing about 12 grams. Germanium itself is classified as a metalloid. Most elements are either metals or nonmetals. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Other major producing countries include Russia and Canada. Germanium is a metal that can be used pure or as a compound. It's hard at room temperature and looks metallic with a shiny silvery grey finish, but it's a semiconductor, without some of the key properties of a metal. One of a group of elements that possess properties of both metals and non-metals. Germanium Metal. Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium is a chemical element with atomic number 32 which means there are 32 protons and 32 electrons in the atomic structure. Technically, germanium is classified as a metalloid or semi-metal.
