Selenium
From the glass industry to electro-optic industries |
|
 |
|
|
|
Selenium is a natural component of copper concentrates and arises during the treatment of anode slimes. The crude selenium at NA is further processed to pure selenium (99.999% purity) or to selenium chemicals by NA’s wholly-owned subsidiary RETORTE Ulrich Scharrer GmbH. |
|
|
The crude selenium serves as the starting material for the production of almost all selenium products. The main part of the annual demand of about 2,000 - 2,500 t of refined selenium is used in the glass industry as a decolourant and colouring agent and at the same time is used as an alloying metal for steel and lead. Likewise it is an essential trace element for mammals and in the form of natrium selenite is added to animal fodder. Selenium is used in foodstuffs and the pharmaceutical industry, e.g. in baby food or vitamin injections, to give metals antique colouring or to produce rectifiers, digital X-ray detectors and high-performance photocopying drums in the electric and electro-optic industries.
