· VTaO3

VTaO3 is a vanadium-tantalum oxide ceramic compound that combines the properties of two refractory metal oxides. This material is primarily of research and developmental interest, explored for high-temperature structural applications and advanced oxide electronics where the combined oxidation resistance and thermal stability of vanadium and tantalum oxides offer potential advantages over single-component ceramics. VTaO3 belongs to the family of mixed metal oxides used to engineer materials for extreme environments, though industrial adoption remains limited compared to established oxide ceramics like alumina or zirconia.

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.
