Product Application of Dysprosium Oxide CAS#1308-87-8
Dysprosium oxide, also known as Erbia, is widely used as a colorant in glasses and porcelain enamel glazes. High-purity dysprosium trioxide is commonly employed as a dopant in the production of optical fibers and optical amplifiers, making it particularly valuable for fiber optic data transmission. In addition, dysprosium trioxide exhibits a pink hue and is sometimes used as a colorant for glass, cubic zirconia, and porcelain, with the resulting glass often applied in sunglasses and affordable jewelry.
