Lithium Tantalate (LiTaO3) is a single-crystal ferroelectric material known for its excellent piezoelectric, pyroelectric, electro-optic, and nonlinear optical properties. Because of its outstanding thermal stability and low acoustic loss, LiTaO3 has become one of the most widely used crystal substrates for surface acoustic wave (SAW) filters, RF communication devices, optical modulators, infrared detectors, and advanced photonics research.
Compared with many other piezoelectric crystals, Lithium Niobate and Lithium Tantalate each offer unique advantages depending on the application. LiTaO3 provides excellent frequency stability, reduced temperature drift, and outstanding acoustic performance, making it an ideal material for high-frequency communication systems.
