· JVASP-116310· LiSe

Lithium selenide (LiSe) is an ionic ceramic compound belonging to the rock salt structure family, combining lithium with selenium to form a brittle, crystalline solid. While primarily a research material rather than a mainstream engineering ceramic, LiSe is studied for applications requiring high ionic conductivity and optical transparency in the infrared spectrum, particularly in solid-state battery electrolytes and infrared optical windows where its wide bandgap and thermal stability become advantageous over conventional alternatives.

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.
