· WTaO3

WTaO₃ is a mixed-metal oxide ceramic compound combining tungsten and tantalum in a perovskite-related crystal structure. This material is primarily of research interest for high-temperature applications and functional ceramics, where its refractory properties and potential photocatalytic or electronic characteristics make it relevant for aerospace, electronics, and advanced manufacturing contexts. While not yet widely adopted in mainstream production, WTaO₃ belongs to a family of tungsten-tantalum oxides being explored as alternatives to conventional refractories and as candidates for next-generation catalysts and energy devices.

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.
