· Yb2O3

Ytterbium oxide (Yb₂O₃) is a rare-earth ceramic compound belonging to the lanthanide oxide family, characterized by high thermal stability and optical transparency in the infrared spectrum. It is primarily used in advanced optics, laser materials, and thermal barrier coatings for high-temperature aerospace applications, where its resistance to thermal shock and chemical inertness are critical advantages over conventional oxides. Yb₂O₃ also serves as a dopant in fiber-optic amplifiers and as a sintering aid in structural ceramics, making it valuable in telecommunications and next-generation thermal protection systems.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
