· JVASP-56717· YbSi2Os2

YbSi2Os2 is an ytterbium silicate oxynitride ceramic compound that combines ytterbium, silicon, and oxygen in a complex ceramic matrix. This material is primarily investigated as a high-temperature structural ceramic and thermal barrier coating candidate, particularly for aerospace applications where thermal stability and oxidation resistance are critical. It belongs to the family of rare-earth silicate ceramics that show promise as advanced alternatives to conventional zirconia-based thermal barrier systems, with the ytterbium component offering enhanced thermal shock resistance and lower thermal conductivity compared to some traditional options.

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.
