Lithium tantalate (LiTaO₃) crystal is an excellent multifunctional material with high application value. LiTaO₃ crystal with its stable chemical properties (insoluble and water), Curie point higher than 600℃, not easy to depolarization phenomenon, low dielectric loss, high detection rate excellent characteristics, become the pyroelectric infrared detector application material.
　　The polished LT chip is widely used in the manufacture of electronic communication devices such as resonators, filters, transducers, etc., especially with its good mechanical and electrical coupling, temperature coefficient and other comprehensive performance, it is used in the manufacture of high-frequency surface acoustic wave devices, and is used in mobile phones, walkie-talkies, satellite communications, aerospace and many other high-end communication fields.
