· ReTaO3

ReTaO3 is a complex metal oxide ceramic composed of rhenium, tantalium, and oxygen, belonging to the family of high-entropy or multi-cation oxide ceramics. This material is primarily of research interest rather than established industrial production, being investigated for applications requiring high-temperature stability and corrosion resistance in extreme environments. The rhenium-tantalium oxide system is notable for potential use in advanced refractory applications, catalysis, or electronic devices where the dual transition metals provide unique chemical and thermal properties compared to single-metal oxide 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.
