Lithium tantalate (LiTaO3) crystal
Lithium tantalate (LiTaO3) crystal is an excellent multifunctional material with high application value. LiTaO3 crystal has become the best choice of pyroelectric infrared detector application materials due to its stable chemical properties (insoluble with water), Curie point higher than 600 ℃, less prone to depolarization, low dielectric loss and high detection rate. Polished LT wafers are widely used in the manufacture of electronic communication devices such as resonators, filters, transducers, etc., especially for the manufacture of high-frequency surface acoustic wave devices with its good electromechanical coupling, temperature coefficient and other comprehensive properties. It is used in many high-end communication fields such as mobile phones, walkie-talkies, satellite communications, and aerospace.
