· JVASP-135336· Li2TaO3

Lithium tantalate (Li₂TaO₃) is a ferroelectric ceramic compound that combines lithium and tantalum oxides, notable for its strong piezoelectric and electro-optic properties. It is primarily used in rf and microwave signal processing devices, optical modulators, and acoustic wave applications where its ability to convert between electrical and mechanical/optical signals is critical. Compared to alternatives like lithium niobate, lithium tantalate offers distinct advantages in specific frequency ranges and temperature stability, making it the preferred choice for high-frequency telecommunications filters, surface acoustic wave (SAW) devices, and integrated photonic modulators in demanding aerospace and defense systems.

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.
