Li3As
ceramic· Li3As
Li₃As is an inorganic ceramic compound composed of lithium and arsenic, belonging to the family of lithium chalcogenides and pnictides. It is primarily of research and development interest rather than a mainstream industrial material, being investigated for potential applications in solid-state electrochemistry and advanced functional ceramics where lithium compounds are leveraged for ionic or electronic 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.
