Factory For Cds Polycrystal 99.999% - Cadmium Sulfide – WMC

Selenium  is amorphous gray  metallic luster solid material, which is becoming black on standing and crystalline on heating, soluble in concentrated nitric acid and in common alkali, lower toxicity. Selenium can burn in air and sent out blue flame, generate two selenium oxides, has also reaction with metal or non-metal directly including hydrogen and halogen.

High purity selenium or high purity oxygen free selenium of 99.999 and 99.9999% 5N 6N purity by the purification process of rectification is primarily used in the preparation of compound semiconductor materials such as Antimony Selenide Sb₂Se₃, Arsenic Selenide As₂Se3, Cadmium Selenide CdSe, Copper Selenide CuSe, Molybdenum Selenide MoSe₂, Tin Selenide SnSe Tungsten Selenide WSe₂, Zinc Selenide ZnSe and Selenide Sulfide SeS₂ etc, selenium drum, photoconductive and photovoltaic material, electrostatic photograph, infrared glass, and other materials for optical devices and instruments.  High Purity Selenium at Western Minmetals (SC) Corporation with 99.999%, 99.9999% 5N 6N purity with oxygen free can be delivered in form of  powder, granule and lump or as customized specification.
