· Re2O3

Rhenium oxide (Re₂O₃) is a rare-earth ceramic compound combining rhenium with oxygen, belonging to the family of refractory oxides. It is primarily investigated in research and specialized high-temperature applications where extreme thermal stability, chemical inertness, and electron-emission properties are required. This material is notable for its potential in high-temperature structural applications and electronic devices, though industrial adoption remains limited compared to more conventional ceramics due to rhenium's scarcity and cost.

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.
