· JVASP-135099· YHfO2

YHfO2 is a hafnium oxide ceramic compound doped with yttrium, belonging to the family of rare-earth-stabilized refractory oxides. This material is primarily investigated in research contexts for high-temperature structural and functional applications, where its chemical stability and thermal resistance are advantageous. It is notable among hafnium-based ceramics for potential use in extreme-environment applications where both mechanical durability and oxidation resistance are critical, such as aerospace thermal protection systems and next-generation nuclear fuel cladding.

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.
