· ErThO3

ErThO3 is a mixed rare-earth oxide ceramic compound containing erbium and thorium. This material belongs to the family of rare-earth thorium oxides, which are primarily investigated in nuclear fuel applications and high-temperature ceramics research due to their thermal stability and radiation resistance. ErThO3 is not widely commercialized in mainstream engineering but represents a research-phase material of interest for advanced nuclear fuel forms and specialized refractory applications where extreme thermal and chemical durability is required.

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.
