Piezoelectric lithium tantalate crystal

Piezoelectric Crystal Lithium Tantalate LT LiTaO3 Crystal Boule Manufacturer

 

Lithium tantalate (LiTaO3) is a perovskite which possesses unique optical, piezoelectric and pyroelectric properties which make it valuable for nonlinear optics, passive infrared sensorssuch as motion detectors, terahertz generation and detection, surface acoustic waveapplications, cell phones and possibly pyroelectric nuclear fusion. Considerable information is available from commercial sources about this salt.

 

Lithium Tantalate (LT, LiTaO3) has unique properties, which as a material finds uses in Electro-Optical and Acousto-Optical applications. These can be : surface acoustic wave devices, bulk acoustic wave devices, piezo-electric transducers and piezoelectric sensors.The 36° and 42 ° cuts of Lithium Tantalate have shown widespread adoption for the telecommunications mobile phone handset market at frequencies from 800 to 2100 MHz. These orientations show an optimized bandwidth / insertion loss trade off in performance and are dominating the ever expanding mobile handset sales.
