· JVASP-10192· LiAs

Lithium arsenide (LiAs) is an inorganic ceramic compound belonging to the III–V semiconductor family, composed of lithium and arsenic elements in a zincblende crystal structure. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, with applications in optoelectronic and photonic devices where its direct bandgap and optical transparency properties are exploited. LiAs is notable for its potential in infrared window materials, nonlinear optical applications, and as a substrate or thin-film component in high-frequency or high-power semiconductor devices, though it remains less common than related compounds (GaAs, InP) due to lithium's high reactivity and the material's challenging synthesis and processing.

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.
