Erbium Oxide
Erbium oxide (Er₂O₃) is a pink powdered rare earth oxide with stable chemical properties, excellent high-temperature resistance and thermal stability. Slightly hygroscopic, it should be stored in a sealed container. It is insoluble in water and slightly soluble in acids.
As a versatile rare earth functional material, erbium oxide plays an irreplaceable role in modern optoelectronic information, advanced manufacturing, environmental catalysis and other fields. It is widely used in optical fiber communication, laser devices, optical infrared materials, high-grade glass and ceramic coloring, up-conversion phosphors, special alloy modification and catalytic additives. It is a core rare earth raw material for optical communication, laser medicine, precision optics and advanced material manufacturing.
UrbanMines supplies custom-grade erbium oxide with typical purities of 99.9% (3N), 99.99% (4N) and higher grades. It features strict impurity control, excellent batch-to-batch consistency, and unique optical, luminescent and material-modifying properties to suit diverse applications.
