TaWO3

ceramic

· TaWO3

TaWO₃ is a mixed-metal oxide ceramic combining tungsten and tantalum in an oxide matrix, belonging to the family of refractory and functional metal oxides. This material is primarily of research interest for applications requiring high thermal stability and chemical inertness, with potential use in high-temperature catalysis, specialized optical coatings, and advanced ceramics where tungsten-tantalum synergy provides improved performance over single-metal oxides. While not yet widely established in mainstream production, compounds in this family are investigated for demanding environments where conventional oxides fail, such as thermal barrier systems and chemical-resistant coatings.

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.
