MSE PRO™ 4N (99.99%) Yttrium Oxide (Y₂O₃) Pieces (2-5mm) Evaporation Materials

Yttrium Oxide (Y₂O₃) is a white crystalline solid that is widely used for phosphors, solid-state laser, and gas lighting. Yttrium oxide thin films have high electric resistivity, good dielectric permittivity, low dielectric losses and good transparency in a wide spectral range with little light diffusion. Due to these properties, yttrium oxide is a prospective material for antireflecting and protective coatings, interference mirrors, and for manufacturing passive components and dielectric layers in multilevel integrated circuits.
