· JVASP-145413· Dy2YTaO7

Dy2YTaO7 is a rare-earth doped pyrochlore ceramic composed of dysprosium, yttrium, and tantalum oxides. This material is primarily of research interest for thermal barrier coating (TBC) applications and advanced refractory systems, where its rare-earth dopant chemistry offers potential improvements in thermal stability and sintering resistance compared to conventional zirconia-based coatings. The pyrochlore structure is notable for its intrinsic low thermal conductivity and high melting point, making it a candidate for next-generation aerospace and power generation applications operating at extreme temperatures.

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.
