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

What is Lithium Tantalate (LiTaO3)?

Lithium tantalate (LiTaO3) is a perovskite which possesses unique optical, piezoelectric and pyroelectric properties which make it valuable for nonlinear optics, passive infrared sensors such as motion detectors, terahertz generation and detection, surface acoustic wave applications, cell phones and possibly pyroelectric nuclear fusion. Considerable information is available from commercial sources about this salt.The LiTaO3 lithium tantalate crystal has >99.99% purity.

2. What is application of LiTaO3?
1) Lithium Tantalate 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.
2) Saw Applications: 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.

For lower bandwidth, higher selection filters other orientations including the 112° rotated cut have shown great promise and are effectively covering the gap between Quartz (Ultra narrow band) and the 36/42 ° (wideband) models.
Both lithium niobate and lithium tantalate can be grown with different properties for differing applications, research projects and production methods. For example wafers free of pyroelectric discharge, 4″ (100mm), orientation 36° or 42°.
