星恒娱乐平台:Germanium Products

Germanium Metal, Chemicals and Alloys


Germanium optical products including chemicals, blanks, optics and windows are offered by Vital Materials’ infrared business unit and Ge wafers are offered by the semiconductor business unit. Germanium production at Vital Materials is vertically integrated. We are able to refine Ge from a wide variety of raw materials even at a very low level of Ge content (less than 0.3%). Starting with such raw material inputs we produce GeO2 grades for electronic, fast soluble, and catalyst applications. We also produce different grades of GeCl4 used in the optical fiber industry.

We offer recycling services and work closely with customers to improve the recycling of germanium and reduce the cost to treat the waste gases at customer’s site. We can treat waste solutions even at a very low germanium level.

Properties

神龙娱乐平台ios www.xadeh.icu Germanium is a brittle, silvery-white, semi-metallic element and 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%). Vital Materials can refine up to 13N purity.


Applications

  • Ge is used mainly in 3 applications: optical fiber, infrared optics, and catalyst in PET synthesis.
  • Optical fiber: In the form of GeCl4, GeO2 is deposited in the core of the fiber. GeO2 has a high refractive index and a low optical dispersion.
  • Infrared optics: Ge is used as lenses or windows. It is used in thermal imaging cameras, hot-spot detection in military and mobile night vision applications.
  • Catalyst: GeO2 is used as a catalyst for the synthesis of polyethylene terephthalate (PET) used to make bottles. This market is mainly located in Asia.
  • Ge is also used electronic applications such as LEDs.
  • A niche application is ultra-high purity single crystal germanium. This is the most pure metal on earth and is used in gamma radiation detectors.
Recycling is an important source of germanium with the main source being the optical fiber industry. Vital Materials has a great capability to recycle germanium and offers recycling services in close cooperation with our customers.
