Product Code : ME-Cd-7N-CU
Discovered in 1817 by Friedrich Stromeyer at Göttingen, Germany. Cadmium is a white metallic element. It is readily accessible as it occurs in concentrated ores and is easily extracted by heating the oxide with carbon and distilling the metal. It has an abundance in the earth's crust of 0.11 ppm. Cadmium has been used in applications as diverse as plating, the manufacture of batteries and as a yellow pigment for paint. However, its high toxicity means that its use is now becoming increasingly restricted.
ATT manufactures highly pure 7N 99.99999% cadmium metal in various forms including pieces, shot, disc, and rod for high technology applications such as the MBE growth of semiconductor crystals or vacuum deposition of thin films. 7N cadmium serves as a precursor for materials like cadmium telluride (CdTe), cadmium selenide (CdSe), cadmium sulfide (CdS), and . These materials are commonly used in photovoltaic solar cells, electronics, and optics, especially in the form of nanoparticles and quantum dots for LEDs and other lighting applications. Examples of available ATT quantum products include CdSe, CdS, CdSe/CdS, CdSe/ZnS; see quantum dots for all available forms. High purity cadmium is also used in the production of scintillation crystals for nuclear radiation detectors like cadmium tungstate (CdWO4) and cadmium zinc telluride (CZT),. ATT' cadmium production processes ensure the absolute minimum amount of impurities, allowing our products to be used as reference materials for impurity analysis and equipment calibration. We also produce 6N (99.9999%) cadmium as well as other lower purity forms.
