PROPERTIES OF DIAMOND, SILICON and GERMANIUM Author - d.w.palmer@semiconductors.co.uk When quoting data from here, please state the reference as D … Tin and Lead are obtained by carbon reduction of their oxides or sulphides. 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.In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. Silicon and germanium can be made by reduction of their dioxides by carbon or calcium carbide in an electric furnace, and then purified further by zone-refining. It is crystalline and brittle and retains its luster in air. Optical properties. Germanium is mainly a byproduct of zinc ore processing. In pure form, the element is a grayish-white metalloid. Germanium, basic physical and chemical properties of the element. The chemical properties of germanium are … Germanium is a chemical element with atomic number 32 which means there are 32 protons and 32 electrons in the atomic structure. Resistivity versus impurity concentration., T = 300 K. (Cuttris [1981]). Source: wikipedia.org License: CC BY 3.0. Germanium is a hard, grayish-white element that has a metallic luster and the same crystal structure as diamond.In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator.In its pure state, this metalloid is crystalline, brittle and retains its lustre in air at room temperature. It is known to initiate healthy oxygen flow in the body tissues and aids in the normal functioning of the immune cells. Germanium is a Block P, Group 14, Period 4 element. Chemical Properties. The models for all four Abstract. It has a melting point of 937.4°C (1,719°F) and a boiling point of 2,830°C (5,130°F). Germanium is solid, shiny chemical element with the symbol Ge. These numbers may well differ considerably from, say, single bond energies in a solid. Germanium has a diamond-like crystalline structure which is hard, lustrous, gray-white, and brittle. Germanium chloride (GeCl 4) and germanium fluoride (GeF 4) can cause irritation to the eyes, skin, lungs and throat. In 2010, the world’s total production of germanium was between 100 and 120 t. This comprised germanium recovered from zinc concentrates, fly ash from burning coal, and recycled material. Materials 3, 034602 – Published 11 March 2019 Compare Arsenic and Germanium on the basis of their properties, attributes and periodic table facts. Notable characteristics . It is also known to maintain a healthy balance between various body functions and is a water-soluble dietary supplement. Notes on the properties of Germanium: Brinell Hardness: converted from Mohs scale Specific Heat: Value given for solid phase. Kelin Kuhn, in High Mobility Materials for CMOS Applications, 2018. Germanium Wafer Process . Germanium and … 1)High purity germanium is obtained during zone refining. Symbol of the germanium element is Ge.
