Lithium tantalate

Mô tả

Mp：>300°C

Lithium tantalate (Li Ta O₃), is a crystalline solid which possesses unique optical, piezoelectric and pyroelectric properties which make it valuable for nonlinear optics, passive infrared sensors such as motion detectors, terahertz generation and detection, surface acoustic wave applications, cell phones and possibly pyroelectric nuclear fusion. Considerable information is available from commercial sources about this crystal.
