ceramic

· YThO3

YThO₃ is a rare-earth oxide ceramic compound combining yttrium and thorium oxides, belonging to the family of refractory ceramics with potential high-temperature stability. This material is primarily of research and developmental interest for extreme thermal environments, such as advanced nuclear fuel matrices, thermal barrier coatings in aerospace propulsion systems, and specialized refractory applications where conventional oxides reach their limits. Its appeal lies in combining rare-earth chemical stability with thorium's neutron absorption characteristics, making it particularly relevant for nuclear engineering and next-generation thermal protection systems.

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.
