Description
Germanium is a chemical element which naturally reacts and forms complexes with oxygen in nature. It has a high index of refraction and low optical dispersion. Germanium can be combined with silicon to form alloys that are rapidly becoming an important semiconductor material, for use in high speed integrated circuits.More related product prices
