· JVASP-10471· K2TaCuSe4

K2TaCuSe4 is an intermetallic compound combining tantalum, copper, and selenium in a potassium-based matrix. This is an experimental material primarily studied in solid-state chemistry and materials research rather than established industrial production; it belongs to the family of complex metal selenides that show potential for thermoelectric, optoelectronic, or photovoltaic applications due to the electronic properties imparted by its mixed-metal composition. Engineers would consider this material in emerging technologies where tantalum's refractory character combines with selenium's semiconductor behavior, though it currently lacks widespread commercial deployment and would require significant development work for practical applications.

Export Control

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.
