· JVASP-135334· LiTaO

Lithium tantalate (LiTaO₃) is a ferroelectric ceramic compound combining lithium oxide and tantalum pentoxide, valued for its electro-optic, piezoelectric, and nonlinear optical properties. It is widely used in telecommunications infrastructure, optical modulators, and photonic devices where its ability to modulate light with applied electrical fields is essential, as well as in acoustic wave devices and precision sensors. Engineers select LiTaO₃ over alternatives like lithium niobate when thermal stability, lower operating voltage, or specific wavelength response is critical, making it particularly important in integrated photonics and high-frequency signal processing applications.

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.
