TbO2
ceramic· TbO2
Terbium dioxide (TbO2) is a rare-earth oxide ceramic material known for its high refractive index and optical transparency in the infrared spectrum. It is primarily used in specialized optics, phosphors, and advanced catalytic applications where rare-earth properties are critical, particularly in environments requiring high thermal stability and chemical inertness. TbO2 is valued in research and emerging technologies for its role as a dopant in luminescent materials and as a component in advanced optical coatings where standard ceramics are insufficient.

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.
