Piezoelectric, SAW Wafers and Crystals
Lithium tantalate (LiTaO3), referred to as LT, belongs to the trigonal system, with a distorted perovskite structure and point group c63vr3c. Lithium tantalate crystals appear to be Colorless or shallow yellowish green. Lithium tantalate (LiTaO3) crystal is an excellent multifunctional material with versatile aptitude. Its general applications include Q-switch in laser applications, pyroelectric detectors in infrared applications, filters, and resonators in the electronic realm.
SAW Grade Lithium tantalate is optimized for Surface Acoustic Wave (SAW) uses with exceptional piezoelectric properties, allowing efficient transferring of mechanical signals into electrical signals. Polished LT wafers are often used for manufacturing a diverse range of SAW devices resonators, filters, transducers, and other electronic communication devices, attributed to their good mechanical and electrical coupling, temperature coefficient, and other comprehensive performance. SAW grade LT finds prominence in fabricating high-frequency surface acoustic wave devices and multiple high-end communication fields such as mobile phones, walkie-talkies, satellite communications, aerospace, and so on.
