· JVASP-78998· TbY3

TbY3 is a rare-earth oxide ceramic compound composed of terbium and yttrium, belonging to the family of sesquioxides with a cubic crystal structure. This material is primarily of research and specialized interest, used in applications requiring rare-earth ceramic properties such as high-temperature stability, optical transparency in the infrared spectrum, and resistance to thermal shock. TbY3 finds niche applications in photonic devices, scintillators for radiation detection, and high-temperature structural components in aerospace and nuclear environments where its thermal and mechanical stability provide advantages over conventional ceramics.

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.
