· ReThO3

ReThO₃ is a rare-earth oxide ceramic compound in the perovskite family, composed of rhenium and thorium oxides. This is primarily a research and development material studied for advanced high-temperature applications, refractory systems, and potential nuclear fuel matrix applications due to its thermal stability and resistance to oxidation. ReThO₃ represents the broader class of complex rare-earth ceramics being investigated for next-generation aerospace, nuclear, and extreme-environment engineering where conventional oxides fall short.

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.
