· WTaO2N

WTaO₂N is an experimental ceramic compound combining tungsten, tantalum, oxygen, and nitrogen—a member of the refractory oxynitride family. These materials are designed to achieve extreme hardness and thermal stability beyond conventional oxides, with particular interest in high-temperature structural applications and wear-resistant coatings. The tungsten-tantalum combination targets aerospace and cutting-tool industries where conventional ceramics approach their limits, though WTaO₂N remains largely in research and development rather than broad commercial production.

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.
