· JVASP-10659· Tm5Re2O12

Tm5Re2O12 is a complex mixed-metal oxide ceramic composed of thulium and rhenium oxides, belonging to the family of rare-earth rhenium compounds. This material is primarily of research and development interest rather than established commercial production, studied for its potential in high-temperature applications where chemical stability and refractory properties are valuable. Its notable density and thermal characteristics make it a candidate material for advanced aerospace, nuclear, or extreme-environment applications, though engineering adoption requires further development and characterization relative to more established ceramic alternatives.

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.
