Overview

Germanium Sputtering Targets (Ge) Information

Germanium, element symbol Ge, atomic number 32, atomic weight 72.64, elemental germanium is a gray-white metalloid, shiny and hard, belonging to the carbon family. Its chemical properties are similar to those of tin and silicon in the same family. It is insoluble in water and has a density of 5.35g. /cm3, melting point is 937°C. Germanium is an excellent semiconductor commonly used in the manufacture of transistors and integrated circuits.
