· JVASP-157290· Pr2DyEr

Pr2DyEr is a rare-earth ceramic compound combining praseodymium, dysprosium, and erbium oxides, belonging to the family of lanthanide ceramics. This material is primarily investigated in research contexts for high-temperature structural and functional applications where rare-earth stabilization enhances thermal stability and oxidation resistance. The combination of these three rare earths offers tuned properties for specialized environments such as aerospace thermal barriers, nuclear fuel matrices, or advanced refractory systems where conventional ceramics degrade.

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.
