· JVASP-106724· TaWSe4

TaWSe₄ is a ternary compound combining tantalum, tungsten, and selenium, belonging to the family of refractory metal chalcogenides. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in advanced electronics and energy storage where the layered crystal structure and mixed-metal composition may offer tunable electronic properties.

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.
