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.
Properties and applications of lithium tantalate litao3 crystal
Lithium Tantalate is one of the most versatile materials. LiTaO3 has numerous applications including electro-optical modulators, pyroelectric detectors, optical waveguide and SAW substrates and piezoelectric transducers due to unique electro-optical, pyroelectric, piezoelectric and acoustic properties, a wide transparency range, and a high optical damage threshold combined with good chemical and mechanical stability.
- Piezoelectric crystal used for SAW devices production
Under certain boundary condition, acoustic wave propagates through the substrate concentrated only on its surface. - Pyroelectric Sensor device material as applying its Pyro-electric properties
Low absorption optical properties (Optical grade LiTaO3) - Optical electronics crystal material used for; Optical modulator, SHG devices and more
LiNbO3 Crystal and LiTaO3 Crystal
Lithium Niobate (LN) and Lithium Tantalate (LT) wafers are mainly used in optic devices and telecommunication equipment,particularly for Surface Acoustic Wave filtering (SAW Filter).
With their excellent chemical and mechanical coupling, the demand is only going up,especially due to ongoing expansion of next generation communication methods.

People also ask
- What is the crystal structure of the LiTaO3?
Lithium tantalate (LiTaO3) is a typical ferroelectric oxide and exhibits unique piezoelectric, electro-optical, and non- linear optical properties that are useful for many applica- tions. 15–18) The trigonal crystal structure (space group: R3c) consists of face-shared LiO6 and TaO6 octahedra
- Why is lithium so good?
lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density for weight. Attempts to develop rechargeable lithium batteries failed due to safety problems.
