· JVASP-110483· Yb2Al2O5

Yb2Al2O5 is a rare-earth aluminate ceramic compound combining ytterbium oxide with aluminum oxide, belonging to the family of rare-earth aluminates used in high-temperature structural and functional applications. This material is primarily investigated for thermal barrier coatings in advanced gas turbines, aerospace engine components, and other extreme-temperature environments where conventional oxides reach their limits. Ytterbium aluminates are notable for their low thermal conductivity and chemical stability at elevated temperatures, making them candidates to replace or supplement yttria-stabilized zirconia (YSZ) in next-generation thermal protection systems, particularly where improved sintering resistance or specific thermal properties are required.

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.
