· JVASP-41120· YbO2

Ytterbium dioxide (YbO2) is a rare-earth ceramic oxide belonging to the fluorite-structure family, characterized by high density and significant stiffness. This material is primarily investigated in advanced thermal and optical applications, including thermal barrier coatings for high-temperature engine components, rare-earth doped laser host materials, and solid-state electrolytes for next-generation fuel cells. YbO2 is notable for its excellent thermal stability, low thermal conductivity, and potential for tunable optical properties when doped with other rare earths, making it particularly attractive where conventional oxides (such as yttria-stabilized zirconia) face limitations in extreme environments or specialized photonic applications.

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.
