· Li2O

Lithium oxide (Li2O) is an inorganic ceramic compound and a key lithium source material used primarily in specialty applications requiring high ionic conductivity or lithium delivery. It serves as a precursor and active component in solid-state electrolytes, advanced ceramics, and glass formulations, particularly where lightweight, high-energy-density materials are needed. Engineers select Li2O-based systems for next-generation battery technologies and thermal/optical applications where its chemical reactivity and lithium content provide functional advantages over conventional oxides.

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.
