The chemical properties of LiTaO3 single crystal are steady and its mechanical are good. Its curie temperature is high. LT crystal has good electro-optical, piezo-electric and pyro-electric properties, so it is an excellent material for the making of SAW devices for color TV filters, infrared pyro-electric detectors and broad band high stability piezoelectric devices. Besides, LT crystal is also one of the light refractive materials that have applications in the laser technique. The Pyro-electric devices made by LT crystal are also connercialized.
