K2TeSe3
ceramic· JVASP-13388· K2TeSe3
K2TeSe3 is a mixed chalcogenide ceramic compound combining potassium, tellurium, and selenium—a layered ionic material belonging to the family of complex metal chalcogenides. This is primarily a research-phase material studied for its electronic and photonic properties rather than an established commercial ceramic; the K2TeSe3 family is of particular interest in solid-state chemistry for potential thermoelectric applications, photovoltaic device layers, and optical sensing due to the tunable band structure afforded by the tellurium-selenium combination.

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.
