· JVASP-100597· DyY3

DyY3 is a rare-earth oxide ceramic compound combining dysprosium and yttrium, belonging to the family of yttrium-based ceramics used in high-temperature and specialized optical applications. This material is primarily investigated for its thermal stability and potential as a thermal barrier coating constituent or in advanced refractory systems where rare-earth dopants enhance performance. The dysprosium addition to yttrium-based formulations is notable for tuning thermal conductivity and thermal expansion characteristics in extreme-temperature environments.

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.
