· JVASP-59770· Yb2Ti2O7

Yb₂Ti₂O₇ is a rare-earth titanate ceramic belonging to the pyrochlore family, composed of ytterbium and titanium oxides. This material is primarily investigated as a thermal barrier coating (TBC) and advanced refractory for high-temperature aerospace applications, where its low thermal conductivity and chemical stability at elevated temperatures offer advantages over conventional oxide systems. The pyrochlore structure provides exceptional resistance to thermal cycling and sintering, making it a promising candidate for next-generation turbine engines and hypersonic vehicle components, though it remains largely in research and development rather than widespread production.

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.
