Description
Germanium is a lustrous, hard, grayish-white metal, chemically similar to its group neighbors silicon. Germanium is is one of the few substances that expands as it solidifies from the molten state. It has the same cubic crystal structure as diamond. It has a high refractive index and is high transparency to infrared radiation. Germanium is a semiconductor and is one of the purest metals on earth (99.99999999999%). Santech produces high purity Germanium products in various shape and size, such as piece, lens, powder, bar. Germanium is mainly used in fiber-optics, infrared optics, compounds, solder and semiconductor.
