Description
Lithium Tantalate Product Overview
Lithium tantalate (LiTaO3) is a colorless, hard crystalline material that is piezoelectric, pyroelectric and electro-optic. Compared with Lithium niobate, it has better temperature stability of frequency and a lower Curie temperature of about 600°C.
Smartphone and RF component producers use lithium tantalate wafers in surface acoustic wave filters, because its temperature stability suits demanding frequency bands. Similarly, sensor producers use it in pyroelectric infrared detectors for motion sensors, flame detectors and thermal imaging, and photonics researchers use it in electro-optic and nonlinear-optical devices.
Furthermore, crystal growers make it from high-purity tantalum oxide and Lithium carbonate. Related lithium materials in our range also include Lithium Titanate and Lithium zirconate.
Key Applications of Lithium Tantalate
Typical uses include, for example:
📱 SAW Filters
