· JVASP-109349· Y2TeS2

Y2TeS2 is a yttrium-based mixed-anion ceramic compound combining tellurium and sulfur. This is an experimental material primarily of research interest rather than an established industrial ceramic; compounds in this family are investigated for potential applications in solid-state electronics, photovoltaic devices, and thermal management systems where layered or mixed-anion structures offer tunable band gaps and ionic transport properties.

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.
