· YbTaO3

YbTaO3 is a rare-earth tantalate ceramic compound combining ytterbium oxide with tantalum pentoxide, belonging to the family of perovskite-related oxides. This material is primarily of research and developmental interest, with potential applications in high-temperature structural ceramics, thermal barrier coatings, and advanced refractory systems where its tantalate chemistry provides enhanced thermal stability and oxidation resistance compared to conventional oxides. Its rare-earth content makes it relevant for specialty aerospace and extreme-environment applications where conventional ceramics reach performance limits.

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.
