Erbium oxide
Er₂O₃ - Pink rare earth oxide for glass, ceramics and optical applications
Erbium oxide (Er₂O₃) is a fine, slightly hygroscopic powder from the group of rare earth compounds. With its characteristic pink to violet color, it is mainly used as a colorant in technical glass and ceramics. It also plays a key role in optical amplifiers, laser systems and fiber optic networks, particularly in telecommunications and medical technology.
PROJECTOR supplies erbium oxide in standardized qualities for industrial and scientific applications - with clear documentation and REACH conformity.
Applications of erbium oxide:
- Coloring of ceramics and glass in violet-pink tones
