LiNbO3
semiconductor· LiNbO3
Lithium niobate (LiNbO₃) is a ferroelectric ceramic compound widely valued for its strong electro-optic, piezoelectric, and nonlinear optical properties. It is a mature, commercially produced material used extensively in telecommunications, photonics, and precision sensing applications where electro-optic modulation, frequency conversion, and acoustic wave generation are critical; engineers select it over alternatives because of its high transparency in the visible and infrared, excellent poling capability, and proven integration into waveguides and bulk optical devices.

Export Control
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.
