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. Our Germanium Sell Price: $915 per half kilogram. 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. One of a group of elements that possess properties of both metals and non-metals. Germanium is mainly a byproduct of zinc ore processing. 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. The development of the germanium 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. Germanium itself is classified as a metalloid. 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. The chemical symbol for Germanium is Ge. Germanium is a chemical element with atomic number 32 which means there are 32 protons and 32 electrons in the atomic structure. It is found quite often in fiber optic networks and infrared optics. Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. 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. Our germanium is sold in half kilogram bar form and wrapped in security packaging with an indication of content, purity, and serial number. Germanium is a silvery white metalloid. Technically, germanium is classified as a metalloid or semi-metal. Germanium is a metal that can be used pure or as a compound. Thus, this compound has an ionic bond.
