product description

Product Application of Dysprosium oxide CAS#1308-87-8

Dysprosium oxide, also known as dysprosia, has the chemical formula Dy₂O₃ and belongs to the rare earth oxide family. It appears as a white, slightly hygroscopic powder, and is highly insoluble with excellent thermal stability. Its crystal structure is cubic below 1870 °C, transitioning to monoclinic and/or hexagonal structures at higher temperatures.


Product Application of Dysprosium oxide CAS#1308-87-8

Dysprosium oxide, also referred to as Erbia, is widely used as a colorant in glass and porcelain enamel glazes. High-purity dysprosium trioxide is commonly adopted as a dopant in the manufacturing of optical fibers and optical amplifiers, holding great value for fiber-optic data transmission. In addition, dysprosium trioxide presents a pink tone and is occasionally used to tint glass, cubic zirconia and porcelain. The processed glass is often made into sunglasses and affordable jewelry.
